Introduction to Usul al-Fiqh
⚖️ Introduction to Usul al-Fiqh — The Key to Ijtihad
﴿ Ask the people of knowledge if you do not know ﴾
— [An-Nahl: 43]
📖 Introduction
📜 Scene: Imam Ash-Shafi'i and the Birth of a New Science
Egypt, 199 AH...
Imam Ash-Shafi'i — may Allah have mercy on him — sat in his teaching circle, surrounded by students from Iraq and Egypt.
One of them asked: "O Imam, why did Abu Hanifa and Malik differ? They are both great imams!"
Ash-Shafi'i smiled and said:
"Their disagreement is a mercy. But one who doesn't know the foundations of reasoning cannot understand why they differed."
The student said: "Then teach us, O Imam!"
Ash-Shafi'i took out pages he had written and said:
"This is 'Ar-Risala'... the first book on the science of Usul al-Fiqh."
🎯 Thus the science of Usul al-Fiqh was born — to organize ijtihad and regulate legal deduction!
📜 Scene: The Firewood and the Snake
A student asked Ash-Shafi'i: "Leave the rules aside and just give us the rulings directly!"
Imam Ash-Shafi'i replied:
"One who seeks fiqh without usul is like one who carries firewood at night with a snake hidden inside!"
⚠️ Fiqh without usul = danger!

📜 Origin of the Science of Usul al-Fiqh
First Stage: Application Without Codification
| Era | Situation |
|---|---|
| 🌙 The Prophet ﷺ | Revelation descended, rulings were clear |
| ⭐ The Companions | Deduced through their intuition and mastery of Arabic |
| 📖 The Tabi'in | Learned from the Companions |
They didn't need to codify rules — they lived them.
Second Stage: Codification
| Event | Details |
|---|---|
| 📚 Ar-Risala | First book on Usul al-Fiqh |
| ✍️ Author | Imam Ash-Shafi'i (d. 204 AH) |
| 🎯 Reason | To regulate ijtihad and systematize reasoning |
📜 Story: Imam Ash-Shafi'i Writes Ar-Risala
The Reason
Abdur-Rahman ibn Mahdi — the imam of hadith scholars — asked him to write a book on the meanings of the Quran and the levels of evidence.
Ash-Shafi'i wrote "Ar-Risala" and sent it to him.
What Did It Contain?
| Topic | Content |
|---|---|
| 📖 The Quran | Its authority and indications |
| 📜 The Sunnah | Its position and categories |
| ⚖️ Ijma | Its conditions and authority |
| 🔗 Qiyas | Its pillars and conditions |
| 📝 Bayan | Its types and levels |
| 🚫 Abrogation | Its rules |
The Impact
Imam Ahmad said:
"We used to curse the people of ra'y (opinion) until Ash-Shafi'i came and enlightened us."
📊 Topics of Usul al-Fiqh
First: Legal Evidences
| Evidence | Definition | Example |
|---|---|---|
| 📖 The Quran | The revealed speech of Allah | ﴿ Establish the prayer ﴾ |
| 📜 The Sunnah | The Prophet's ﷺ words or actions | "Pray as you have seen me pray" |
| 🤝 Ijma | Consensus of the mujtahids | The obligation of the five prayers |
| 🔗 Qiyas | Linking a case to another | Prohibiting nabidh like wine |
Second: Indications of Terms
| Chapter | Content |
|---|---|
| 📝 General and Specific | What includes all vs. what specifies some |
| ⛓️ Absolute and Restricted | Term without condition vs. conditioned |
| ❓ Ambiguous and Clear | What needs clarification |
| 📜 Literal and Figurative | Original meaning vs. derived |
Third: Legal Rulings
| Ruling | Definition | Example |
|---|---|---|
| ✅ Obligatory (Wajib) | Rewarded if done, punished if left | The five prayers |
| 💚 Recommended (Mandub) | Rewarded if done, not punished if left | Regular sunnahs |
| ⚪ Permissible (Mubah) | No reward or punishment | Eating and drinking |
| 🟡 Disliked (Makruh) | Rewarded if left, not punished if done | Praying while sleepy |
| ❌ Prohibited (Haram) | Rewarded if left, punished if done | Riba and zina |
⚖️ Difference Between Fiqh and Usul al-Fiqh
| Fiqh | Usul al-Fiqh |
|---|---|
| Practical rulings | Methodological rules |
| Ruling of Friday prayer | Commands indicate obligation |
| Fruit of ijtihad | Tool of ijtihad |
| The building | The foundation |
🎯 Example:
- The faqih says: "Friday prayer is obligatory"
- The usuli says: "Commands indicate obligation"
🎯 Contemporary Cases
📱 Case 1: Scholars' Disagreement on Photography

The disagreement is in application (tahqiq al-manat):
| Opinion | Reasoning |
|---|---|

💡 Usul helps us understand: each has evidence!

Applying the rule of Istihlak (dissolution):
| Condition | Explanation |
|---|---|
| 🔬 Complete transformation | The alcohol changed its nature |
| 💧 Minimal quantity | Does not cause intoxication |
