Arabic hadith text
حَدَّثَنَا يَحْيَى بْنُ خَلَفٍ أَبُو سَلَمَةَ، قَالَ حَدَّثَنَا عَبْدُ الأَعْلَى، عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ، حَدَّثَنِي عَبْدُ اللَّهِ بْنُ أَبِي بَكْرٍ، عَنْ أُمِّ عِيسَى الْجَزَّارِ، قَالَتْ حَدَّثَتْنِي أُمُّ عَوْنٍ ابْنَةُ مُحَمَّدِ بْنِ جَعْفَرٍ، عَنْ جَدَّتِهَا، أَسْمَاءَ بِنْتِ عُمَيْسٍ قَالَتْ لَمَّا أُصِيبَ جَعْفَرٌ رَجَعَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ إِلَى أَهْلِهِ فَقَالَ ‏"‏ إِنَّ آلَ جَعْفَرٍ قَدْ شُغِلُوا بِشَأْنِ مَيِّتِهِمْ فَاصْنَعُوا لَهُمْ طَعَامًا ‏"‏ ‏.‏ قَالَ عَبْدُ اللَّهِ فَمَا زَالَتْ سُنَّةً حَتَّى كَانَ حَدِيثًا فَتُرِكَ

Asma’bint ‘Umais said

“When Ja’far was killed, the Messenger ofAllah (ﷺ) went to his family and said: ‘The family of Ja’fararebusy with the matter of their deceased, so prepare food forthem.’” (One of the narrators) Abdullah said: "That continued to be the Sunnah, until innovations were introduced, then it was abandoned."
