حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، وَمُحَمَّدُ بْنُ الصَّبَّاحِ، قَالاَ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ جَعْفَرِ بْنِ خَالِدٍ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ جَعْفَرٍ، قَالَ لَمَّا جَاءَ نَعْىُ جَعْفَرٍ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ اصْنَعُوا لآلِ جَعْفَرٍ طَعَامًا. فَقَدْ أَتَاهُمْ مَا يَشْغَلُهُمْ أَوْ أَمْرٌ يَشْغَلُهُمْ ‏"‏ ‏.‏

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."
