      they Developed
   نَشَأَةُ القَوَاعِدِ الفِقْيِيَّةِ وَ كَيْفَ تَطَوَّرَت
  The Foundation stage (مَرْحَلَةُ نَشَأَةِ القَوَاعِدِ
      الفِقْيِيَّةِ)
The foundation of  Al- Qawa'id Fiqhiyyah   is
  primarily found in the Noble Qur'an, the authentic Sunnah of the
  Messenger of Allah صلى الله عليه وسلم , the saying of the Prophet (Sahabah ,
  the companions), and the saying of the Tabi'in (Followers of the
  Companions).
Examples:
Narrated Abu Sa'l'd Al- Khudri'
  Allah's Messenger said:
لا ضرر ولا ضِرار في الإسلام
  ( la darar wa la dirar fi al-Islam) Islam forbids people to cause detriment on
  themselves or on others"10
'Umar Ibn Al-Khattab said:
مقاطع الحقوق عند الشروط
  (Maqati' al-huquq  'ind ash-shurutt)  Rights decisively lean on
  provisions."11
'All Ibn Abu Talib said:
من قاسم الربح فلا ضمان عليه
  (Mann qasam ar-rebh fala  daman 'alaih) There is no guarantee upon whom
  shares profits"12, and so on.
From the (tabi'in, Followers 
  of the Companions), Shuraih Ibn Al-Harith Al Kindiy (d.76/695) said:
(Mann
  sharat ta'i'an ghair mukrah fahuwa 'aliyh) Whoever optionally, and without
  coercion, stipulates a certain condition on himself, must fulfill this
  condition."
Jubair Ibn Nu'aim13 said:
من أقر عندنا بشيء ألزمناه إياه 
(Mann
  aqarr 'indana be shai' alzmnah iyah) Whoever states something, should be
  responsible for it"14, and so on.
After Tabi'in (the followers
  of the Companions), many legal maxims were initiated or repeated by different
  scholars in their books. Examples can be found in the book: Al- Kharadj,
  written by Imam Abu Yusuf15:
التعزير إلى الإمام على قدر عِظَم الجرم وصِغَرهِ
(At-ta'zir ila al-imam 'alaqadr 'izam
  al-jurm wa seghareh) Discretionary punishment entrusted with the state leader
  relies on the extent of the crime."16
 كل من مات من المسلمين لا وارث له فإن ماله يكون لبيت المال
(Koll mann
  mat min al-Muslimin la warith lahfa maluh le bait al-mal) Should a Muslim die
  and have no one to inherit him, his wealth is assigned to the public treasury
  of a Muslim state."17
Other examples can be found in the book:
  Al-Asl. writte n by Ima m Muha mmad Ibn Al- Hasan18
    كون الواحد حجة في الدين اذا كان عدلا
(Kawn
  al-wahid hujjahfi amr ad-din idha kan 'ad/) For one's words to be accepted,
  one must be honest and have a good reputation in the matter of religion"19
 
In
  the same manner, Imam ash-Shafi'i' (d.204/819) wrote his book Al-Omm from
  which many Qawa'id can be extracted:
الرخص لا يتعدى بها عن مواضعها
(Ar-rukhas
  la yuta'd beha mawadi'ha) Allowances of Allah must not go beyond their
  limits"20
الرخص لا تكون الا لمطيع فأما العاصي فلا
 (Ar-rukhas la takun ilia le muti
  'fa  amma al 'asiy/ala ) The allowances of Allah are restricted for the
  obedient only."21
Ma'alim As-Sunan. written by Imam Suleiman
  Ahmad Ibn Muhammad Al Khattabi Al-Bustiy (d.388/998), is one of many books
  that explained the Sunnah and contained many of the legal maxims. An example
  would be:
الشك لا يزاحم اليقين
(Ash-shakk
  la yazham  al-yaqin) Doubt does not refute certainty."
The
  author deducted it from the Hadith:
 يأتي أحدَكمُ الشَّيطانُ في الصَّلاةِ, فينفخُ في مقعدتِه ، فيُخيَّلُ إليهِ أنَّهُ أحدَثَ , ولَم يُحدِثْ , فإذا وجدَ ذلِك فلا ينصرِفْ حتَّى يسمعَ صوتًا أو يجدَ ريحًا
Narrated 'Ali that Sufyan that Az-Zuhri that Sa'id ibn al- Musiyb that 'Abbad
  Ibn Tamim's cousin that the Prophet had advised a person who would continuously imagine something
  happening to him in his Salah. "Should an individual imagine something happening to him in his Salah, he should not leave his Salah unless he hears
  sound or smells something".22
Another example is the book, At-Tamhed lema fi Al-Muwatta' men Al- Ma'ani wa Al-Asanid. written by Imam Abu
  'Umar Ibn 'Abdul-Bar Al-Qurtubiy Al-Malikiy (d.463/1070) also paid more
  attention to Al-Qawa'id Al-Fiqhiyyah.  Here, one of its Qawa'id :
من وجب له شيء من الأشياء لم يدفع عنه ولم يتصور عليه الا بإذنه
(Mann
  wajab lahu shai' men al-ashya' lam yudfa;   'anh wa lam yutasawr
  'alaih illa be idhnih) Should one have a right, this right must not be
  extracted from him except by his permission."
The author inferred
  it from the Hadith:
أن رسول الله - صلى الله عليه وسلم - أتي بشراب فشرب منه ، وعن يمينه غلام ، وعن يساره الأشياخ ، فقال للغلام : أتأذن لي أن أعطي هؤلاء ، فقال : لا والله يا رسول الله ، لا أوثر بنصيبي منك أحدا ، قال : فتله رسول الله - صلى الله عليه وسلم - في يده .
Narrated 'Abdullah ibn
  Yusuf that Malik that Abi Hazim ibn Dinar that Sahl Ibn Sa'd as-Sa'idi said:
A drink of (milk, water, and so on) was offered to Allah's
  Messenger and after he drank some of it, he
  wished to give the elder persons sitting on his
  left side first, but there was a young man (or a boy) sitting on his right
  side. Allah's Messenger asked the young man,
  "Could I be excused from giving you first (the drink)?", "No, by Allah, 0
  Allah's Messenger I cannot prefer others to drink after you directly
  over me," the you ng man has kindly given an excuse. Therefore, Allah's
  Prophet gave it to him.23
 مَرْحَلَة تَقْييدِ القَوَاعِدِ الفِقْيِيَّةِ
The Fourth Century 
History has testified that jurists of
  Hanafiy Madhhab preceded others in collecting, paraphrasing and recording
  Al-Qawa'id Al-Fiqhiyyah and the Dawabit (controllers) of Fiqh. Imam
  Abu Tahir Ad- Dabas 24had collected seventeen Qa'idah Qulliyyah as Imam
  As-Seyuti and Imam Ibn Nujaim told us. Imam Al-Karkhiy, Ad-Dabas's friend,
  might have recorded these Qawa'id and added to other Qawa'id to be thirty-
  nine in his book ( Usul Al-Karkhiy ) which was the first work in this field.
  Furthermore, Imam Muhammad Ibn Harith Al Khushni Al-Malikiy (d.361/971)
  wrote a book under the title "Usul Al-Futya" including more Qawa'id 
  and wide-ra nging subjects  of Fiqh  .
The fifth
  Century
In that time, Imam Ad- Dabusiy 'Ubaiydullah Ibn 'Umar Ibn 'Isa
  Al-Qadl' called Abu Zaid Ad-Dabusiy (d.430 /1038) added a great scientific
  fortune in his book Ta'sis An- Nazar. In addition, Imam Al-Ha ramain
  'Abdul-Malik Ibn 'Abdullah Ibn Yusuf Ash-Shafi'iy Imam Al- Haramain
  Al-Juwaini (d.478/1085) methodologically planted a series of Al-Qawa'id
  Al-Fiqhiyyah in his book Al Gheyathi.
The Sixth Century 
This period had more than a few written works, following are some of them:
a) Idah Al-Qawa'id by Imam 'Aia'-ud- Dl'n Muha mmad Ibn Ahmad As Samarqandiy (d.570/1174) and,
b) Al-Muqadimat wa Al-Mumahidat by Imam Abu Al-Wall'd Muham mad Ibn Ahmad Ibn Rushed (d.520/112 6).
Besides, Imam Fakhr-ud-Dl'n Al-
  Farghaniy Al- Hasa n Ibn Mansur Ibn Mahmud, called Qadikhan, (d.592/1159) were
  among those who explicated books of Al Qawa'id Al- Fiqhiyyah.
The
  Seventh Century 
The science of Al-Qa wa'id Al- Fiqhiyyah in this period, had crystallized but had not yet reached maturity. The greatest writers at this time were:
a) Imam Mu'l'n-ud- Dl'n Abu Muha mmad Ibn Ibrahl'm Al-Jajarmiy As Sahlakiy Ash-Shafi'iy (d.613/1216) in his book Al-Qawa'id Al Fiqhiyyah fi Furu' Ash-Shafi'iyyah ,
b) Imam 'Izz-ud- Dl'n Ibn 'Abdus-Salam (d.660/1261), in his book Qawa'id Al-Ahkam fi Masalih Al-Anam.
c) Imam Muha mmad Ibn 'Abdullah Ibn Rashid Al-Bakri Al-Qafasi' (d.736/1336) in his book, Al-Madhhab fi Dabt Qawa'id Al-Madhhab and,
d) Imam Abu Al-Mahamid Mahmud Ibn Ahmad Ibn 'Abd-us-Sayed Jamal ud- Din Al-Husairi (d.363/973) in his book At-Tahrir Sharh Al-Jami' Al  Kabir.
The book, in addition, Al-Majmu'
  Sharh Al-Muhadhhab by Imam Abu Zakariyyah  Muhiy-ud- Din Yahya  Ibn
  Sharaf an-Nawawl' (d.676/1277) and the book Anwar Al-Boruq fi Anwa' Al- Furuq
  by Imam Shihab-ud-Dl'n Al-Qarafiy is said to have numbers of Qawa'id .
The
  Eighth Century 
Recording the science of Al-Qawa'id Al- Fiqhiyyah
  flourished in this century and it became the golden age of this field of
  knowledge, and scholars of Shafi'iyyah were in advance of other scholars.
  Examples were as follows:
a) Al-Ashbah Wan-Naza'ir by
  Ibn Al-Wakil Ash-Shafi'iy( d.716/1316),
b) Majmu' 
  Al-Fatawa  by Ahmad  Ibn  'Abdul-Hallm  Ibn 
  'Abdus-Salam  Ibn 'Abdullah  Ibn  Tiymiyyah 
  'Abdul-Hallm  Ibn Tiymiyyah  (d.728/1350),
c) 
  Al-Qawa'id  by Al- Maqqa riy Al-Malikiy (d.758/1328),
d)
  Al-Ashbah  Wan-Naza'ir by Tajj-ud- D1n As-Subkkiy  (d.771/1369),
e)
  Al-Manthur fi Al-Qawa'id by Badr-ud-D1n Muha mmad Ibn Bahadir Ibn
  'Abdullah  Az-Za rkkashiy   (d.794/1391),
f) Al-Qawa'id fi Al-Fiqh by Zain-ud-D1n 'Abdur-Rahman Shihab-ud- D1n Ahmad Ibn Rajah Al-Ha nbaliy (d.794/1391) and,
g) Al-Qawa'id fi Al-Furu' by 'Ali Ibn 'Uthman
  Al-Ghazzi, the Damascene and Hanafiy, (d.799/1369) are the most significant
  books of this stage.
The Ninth Century 
Like the previous phase, a significant numbe r of new books were authored:
a) Al-Ashbash Wan-Naza'ir by Ibn Al- Mulaqqen Seraj-ud-Din Abu Hafs 'Umar Ibn Abu Al- Hasan 'All Ibn Ahmad Ibn Muham mad Ibn 'Abdullah (d.804/1401),25
b) Asna Al-Maqasid fi Tahrir Al-Qawa'id by Ibn Al- Khadr Muhammad Ibn Muhammad Ibn Muhammad Az-Zubairiy Al-'Aithariy (d.808/1405),26
c)    Al-Qawa'id  Al-Manzumah 
  by  Shihab-ud- Din  Ahmad  Ibn  Muhammad Ibn 'Imad Al-
  Masriy Ibn Al-Ha'im Al- Maqdesiy (d.815/1412),27
d)   
  Al-Qawa'id by Taqiy-ud- Din Abu Bakr Al-Husniy (d.829/1452),28
e)   
  Nazm Adh-Dhkha'ir fi Al-Ashbah Wan-Naza'ir by Sharaf-ud-Din 'Abdur-Rah man Ibn
  'All Ibn Ishaq Al-Khallliy Al- Muqdesiy, called Shuqair,  
  (d.876/1471)   and,
f)    Al-Qawa'id  
  wa Ad-Dawabit  by Yusuf  Ibn  Hasan  Ibn Ahmad 
  called  Ibn  Al-Mabred  As-Salahi 'Abdul-Hadi (d.880/1475).
The
  Tenth Century 
a)    Imam   
  Jalalud-d1n    as-Seyut1  (d.911/1505)  
  who    collected    scattered Qawa'id in
  his book Al-Ashbah Wan-Naza'ir,
b)    Imam Abu Al-
  Hasa n Ar-Raqaq An- Naj 1biy Al- Malikiy (d.912 /1506) who rearra nged Al-Qa
  wa'id from the old books and
c)    Imam Ibn Nujai m (d.970
  /1562) were the prominent scholars who emerged during this century.
Recording, organizing and paraphrasing Al-Qawa'id Al-Fiqhiyyah gradually became
  successful, but they were mixed with other sciences. The most significant
  event of the last part of the 11th century A.H. was the collecting of Al-Qa
  wa'id Al-Fiqhiyyah and putting them in Majallat Al-Ahkam Al-'Adliyyah by the
  prominent jurists in the age of Sultan 'Abdul-'Aziz Khan Al-'Uthmaniy so as
  to be applied as laws in the different courts. The Majalah helped to
  instigate and further the movement of Al-Qawa'id Al-Fiqhiyyah. It included
  1851 articles in 16 volumes, and was explicated more than once in different
  works:
a)    Mir'at Majallatul-Ahkam Al-'Adliyyah by Su'ud
  Afand1 in Arabic, but the Qawa'id were written in Turkish, and published in
  (1299/1881).
b)    Durar
  Al-Hukkam Sharh Majallat Al-Ahkam by 'All' Hiydar, it was translated from
  Turkish to Arabic by Fahhmi Al-Husaini', a lawyer.
c)   
  Sharh Al-Majallah was recorded by Imam Khalid Ibn Muhammad Ibn 'Abdus-Sattar
  Al-Atasi (d.1326/1908) and  his  son  Muhammad completed this
  work after his father's death.

مَصَادِرُ وَ مُيِمَّةُ وَ مَكَانَةُ القَوَاعِدِ الفِقْيِيَّةِ 
The Sources, Mission and Position of Al-Qa 'idah Al-Fiqhiyyah  in
      issuing Fatwa
 مَصَادِرُ القَوَاعِدِ الفِقْيِيَّة
  
  
  Sources of Al-Qawa'id Al-Fiqhiyyah
1. The Quran and the Sunnah text(I):
a.   
  Ayah (verse) or Hadith that has been taken as a Qa'idah Fiqhiyyah or,
b. Ayah or Hadith that includes general ruling from which the jurists obtained a Qa'idah Fiqhiyyah or more.
Examples for (a):
From the
  Quran:
Allah says in the Noble Qur'an:
وَأَحَلَّ اللَّهُ الْبَيْعَ وَحَرَّمَ الرِّبَا ۚ
(
  .....and Allah has permitted trading and forbidde n Riba, usury)) 52 (Surah 2. Al-Baqa rah, Ayah 275)
This Ayah permits lawful trading and
  forbids usury.
From the Sunnah:
 أنَّ النَّبيَّ صلَّى اللهُ عليه وسلَّمَ بَعَثَهُ إلى اليَمَنِ، فَسَأَلَهُ عن أشْرِبَةٍ تُصْنَعُ بهَا، فَقالَ: وما هي؟ قالَ: البِتْعُ والمِزْرُ -فَقُلتُ لأبِي بُرْدَةَ: ما البِتْعُ؟ قالَ: نَبِيذُ العَسَلِ، والمِزْرُ: نَبِيذُ الشَّعِيرِ- فَقالَ: كُلُّ مُسْكِرٍ حَرَامٌ.
  Narrated Is-haq that Khalid that Ash-Shiybani that the father of
  Sa'id ibn Burdah that Abu Musa Al-Ash'ari:
  Allah's Messenger  said,: "Kull musker haram [Every musker (whatever
  intoxicates or causes
drunkenness) is Haram (unlawful)] 53."
An
  Example for (b):
The maxim, Qa'idah,:
الأمور بمقاصدها
(Al-umur
  be maqasideha) Acts are judged by the intention behind them or take the will
  for the deed/'
Is extracted from a numbe r of texts from the Qur'an
  and the Sunnah.
2. The Analogy Qiyas:
The maxim, Qa'idah, :
 المجهول كالمعدوم
(Al-majhul
  kal-ma'dum) An unknown object is similar to a nonexistent one,"
if
  an unknown object was compared against a nonexistent object, both of them
  take the same judgment since neither can be obtained.
3. The Indication Dalalah:
Istidlal literally means asking for evidence or proof54; however, it
  practically (in this field) means giving evidence or proof which does not
  directly extracted from a text (from the Qur'an or Sunnah),
  Ijma' (consensus) or Qiyas.
An example of
  that is a maxim, Qa'idah says:
الأصل براءة الذمة
(Al-asl
  bara'tudh-dhimmah ) Non-liability or man is absolved from guilt, blame or
  responsibility for any wrong deed in principle,".
4. The Favouring Tarjih:
When evidence hinders one another, one
  of them tends to take priority over the other, in the eyes of the Faqih (a jurist). 55
  
مُهمَّةُ القَوَاعِدِ الفِقْهيَّةِ
Mission of Al-Qawa'id Al-Fiqhiyyah
"Familiarity with the Qawa'id Fiqhiyyah may save a person from
  committing the branches ( Furu and particles juz'iyat) to his memory," Imam
  Al-Qarafiy said.56 Imam Az-Zarkkashiy, in addition, stated that Al-Qa wa'id
  Al-Fiqhiyyah are the way to preserve the Fiqh and assemble its different
  parts. 57 Imam As Seyutistated that Al-Qawa'id Al-Fiqhiyyah enable a jurist to answer dissimilar Nawazel, new questions related to recent
  events).57
The mission of Al-Qawa'id Al-Fiqhiyyah can be
  stated as follows:
i.    To Simplify and to assemble
  the branches (Furu of Islamic Fiqh.
ii.   
  To extract and organize different branches of rulings (Ahkam) under one topic
  in order to avoid contradictions.
iii.    To assist
  scholars to infer replies to Na wazel.
iv.    To
  allow scholars to compare between various Madhahib.
v.   
  To prove that Islamic Fiqh  encompasses any community, everywhere
  anytime and everytime.
مَكَانَةُ القَواعِدِ الفِقْهيَّةِ فِى إِصْدَارِ الفَتْوَى وَالأحَْكَامِ هل
يجوز جعل القاعدة الفقهية دليلا يستنبط منه الحكم؟
وما مدى اعتمادها فى الإفتاء والقضاء؟
The Position of Al
  -Qawd 'id Al-Fiqhiyyah in Issuing Fatwa and Ahkam Is it permissible to
  consider Al-Qa wa'id Al- Fiqhiyyah as one of the Adellah Shar'iyyah?59
Can
  Al-Qa wa'id Al- Fiqhiyyah be among the proofs that infer Ahkam,
  Judgments)?
Al-Qa wa'id Al-Fiqhiyyah have been the focus of
  scholars' attention, and their Fatwa (legal opinions of Islamic Law)
  continuously until our prese nt time. "Numerous Qawa'id Fiqhiyyah included in
  the books of Imams (who give Fatwa) and the magistrates are not in the books
  of Usul Al- Fiqh," Imam Al Qarafiy stated.60
Is it
  permissible to consider Al-Qawa'id Al-Fiqhiyyah as one of the evidences
  (Adellah Shar'iyyah) for judgments?
Sheikh Mustafa Az-Zarqqa stated that Al-Qawa'id Al-Fiqhiyyah handle Fiqh and have many
  exceptions, but they are not Nusus (texts from the Qur'an or Sunnah)
  used for judgments.61
