“I was witness that ibn abu Layla’ judged in the case of a man who had designated the income of a house for his relative without the mention of time limit. The man died and his heirs came to ibn abu Layla’ and his relative for whom the house was designated. Ibn abu Layla’ said, ‘I see that it must be left as its owner has left.’ Muhammad ibn Muslim al-Thaqafiy then said, ‘Ali ibn Abu Talib, ‘Alayhim al-Salam, judged in the same Masjid opposite to what you have judged.’ He asked, ‘How do you know that?’ He replied, ‘I once heard abu Ja‘far (a.s.), saying, “’Amir al-Mu’minin judged to return what is kept on hold and to execute the rules of inheritance.’” Ibn abu Layla’ then asked, ‘Is this written in a book with you?’ He replied, ‘Yes, it is in a book.’ He said, ‘Send to bring it.’ Muhammad ibn Muslim said, ‘I will do so upon the condition that you will not read anything else in the book besides this Hadith.’ He said, ‘That is up to you.’ He (the narrator) has said that he showed him the Hadith from abu Ja‘far (a.s.), in the book and he took his judgment back.’”
