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!

Ash-Shafi'i wrote "Ar-Risala" and sent it to him.
