Translation
Narrated Ibn 'Abbas (RA)

The Prophet (ﷺ) said: "If people were given whatever they claimed (in disputes), some people would claim the lives and wealth of others; but the oath (of denial) must be taken by the defendant."[Agreed upon]. al-Baihaqi has reported with a Sahih (authentic) chain of narrators: "But the proof (Bayyinah) lies on the one who is making the claim, and the other (Yamin) must be taken by the one who rejects the claim."

Comment

Judgments: Commentary on Hadith from Bulugh al-Maram 1423

In the name of Allah, the Most Gracious, the Most Merciful. This noble hadith establishes fundamental principles of Islamic judiciary procedure that protect society from false claims and preserve justice.

The Danger of Unsubstantiated Claims

The Prophet (ﷺ) warns that if judges were to automatically grant every claim without evidence, society would descend into chaos where people would falsely claim each other's lives and properties. This demonstrates the wisdom of Shariah in establishing procedural safeguards.

The Two Foundational Principles

First: "Al-Bayyinah 'ala al-Mudda'i" - The burden of proof lies upon the claimant. This protects defendants from having to prove their innocence against baseless accusations.

Second: "Al-Yamin 'ala man Ankar" - The oath of denial is upon the one who rejects the claim. When the claimant cannot produce evidence, the defendant may clear themselves through a solemn oath before Allah.

Scholarly Interpretation

Imam al-Shafi'i and other jurists explain that these principles apply to all civil disputes involving property, rights, and financial matters. The combination of these two rules - requiring evidence from claimants and allowing oaths from defendants - creates a balanced judicial system that deters false claims while providing legitimate means for establishing truth.

Practical Application

This ruling teaches Muslims to be precise in their claims and cautious in their accusations. It reminds judges to require clear evidence before ruling in favor of any claim, thus upholding justice and preventing oppression through legal means.
