Hadith.5581 - Muhammad ibn Abi Umayr narrated from Umar ibn Udhaynah, who said: I was present with Ibn Abi Layla when Imam ruled on a case involving a man who had allocated the yield (ghallah) of his house to one of his relatives without specifying a time limit. When the man passed away, his heirs came before Ibn Abi Layla, along with the relative who had been granted the house's yield. Ibn Abi Layla said: "I see that it should remain as the owner had left it." Muhammad ibn Muslim Al-Thaqafi responded, "Indeed, Imam Ali ibn Abi Talib , peace be upon him, ruled differently in this very mosque than what you have ruled." Ibn Abi Layla asked: "And what knowledge do you have of this?" Muhammad ibn Muslim replied: "I heard Abu Ja'far Imam Muhammad ibn Ali Al-Baqir , peace be upon him, say: 'Imam Ali ibn Abi Talib , peace be upon him, ruled to revoke the habis (temporary endowment) and enforce the distribution of inheritance.'" Ibn Abi Layla then asked: "Do you have this in a book?" He replied: "Yes." Ibn Abi Layla said: "Then send for it and bring it to me." Muhammad ibn Muslim stipulated: "On the condition that you look only at this specific narration in the book." Ibn Abi Layla agreed: "That is acceptable." Muhammad ibn Muslim brought the book and showed him the narration from Abu Jafar Imam Muhammad ibn Ali Al-Baqir , and Ibn Abi Layla retracted his judgment.
