Analogical Reasoning (Qiyas)
🔗 Qiyas — Analogical Reasoning
﴿ So take warning, O people of insight ﴾
— [Al-Hashr: 2]
📖 Introduction
📜 Scene: Omar and the Date Wine
Medina, during the caliphate of Omar...
A man came to Omar ibn al-Khattab — may Allah be pleased with him — and asked:
"O Commander of the Faithful, we have a drink made from dates called nabidh. Is it permissible?"
Omar gathered the Companions and said:
"Wine was forbidden because it intoxicates and prevents from prayer. Does this nabidh intoxicate?"
They answered: "Yes, if one drinks a lot of it."
Omar ruled:
"Whatever intoxicates in large amounts is forbidden even in small amounts. It has the same cause as wine!"
🎯 This is qiyas — extending a ruling from an original case to a new case because they share the same cause!
📜 Scene: Ali and Reasoning
Ali ibn Abi Talib — may Allah be pleased with him — was asked:
"Did the Messenger of Allah ﷺ specify you with something special?"
Ali replied:
"No, except what is in this sheet... and a man's understanding of his religion."
💡 Qiyas is part of understanding the religion!

From the Sunnah
The Prophet ﷺ said to a man who questioned paternity:
"Do you have camels? What is their color? Is there a grey one among them? From where did it get its greyness?"
The man said: "Perhaps it's atavism."
The Prophet ﷺ said: "And perhaps this child is also atavism."
— [Al-Bukhari and Muslim]

📜 Story: Abu Bakr and Analogizing Zakat
The Cause
After the Prophet ﷺ passed away, some tribes refused to pay zakat.
Some Companions said: "They are still Muslims, how can we fight them?"
Abu Bakr's Qiyas
Abu Bakr said:
"By Allah, if they withhold from me even a rope they used to give to the Messenger of Allah ﷺ, I will fight them for it! Zakat is the right of wealth, just as prayer is the right of the body!"
🎯 He analogized the obligation of zakat to the obligation of prayer!
