Sunan an-Nasai
أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، قَالَ حَدَّثَنِي الزُّهْرِيُّ، عَنِ الْحَسَنِ، وَعَبْدِ اللَّهِ، ابْنَىْ مُحَمَّدٍ عَنْ أَبِيهِمَا، أَنَّ عَلِيًّا، بَلَغَهُ أَنَّ رَجُلاً، لاَ يَرَى بِالْمُتْعَةِ بَأْسًا فَقَالَ إِنَّكَ تَائِهٌ إِنَّهُ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْهَا وَعَنْ لُحُومِ الْحُمُرِ الأَهْلِيَّةِ يَوْمَ خَيْبَرَ .
It was narrated from Al-Hasan and 'Abdullah, the sons of Muhammad, from their father, that 'Ali heard that a man did not see anything wrong with Mut'ah (temporary marriage). He said: "You are confused, the Messenger of Allah forbade it, and the meat of domestic donkeys on the day of Khaibar."
