Hadith 1969
حَدَّثَنِي عَبْدُ الْجَبَّارِ بْنُ الْعَلاَءِ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا الزُّهْرِيُّ، عَنْ أَبِي عُبَيْدٍ، قَالَ شَهِدْتُ الْعِيدَ مَعَ عَلِيِّ بْنِ أَبِي طَالِبٍ فَبَدَأَ بِالصَّلاَةِ قَبْلَ الْخُطْبَةِ وَقَالَ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَانَا أَنْ نَأْكُلَ مِنْ لُحُومِ نُسُكِنَا بَعْدَ ثَلاَثٍ .
Abu Ubaid reported:
I was with 'Ali b. Abi Talib on the occasion of the 'Id day. He started with the 'Id prayer before delivering the sermon, and said: Allah's Messenger (ﷺ) forbade us to eat the flesh of our sacrificial animals beyond three days.
