Hadith 4:211
‘Abdallah b. Ja'far told that when the news of Ja'far’s death came the Prophet said, “Prepare food for Ja'far’s family, for they have heard something which takes up their whole attention.” Tirmidhi, Abu Dawud and Ibn Majah transmitted it.
وَعَنْ عَبْدِ اللَّهِ بْنِ جَعْفَرٍ قَالَ: لَمَّا جَاءَ نَعْيُ جَعْفَرٍ قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسلم: صانعوا لِآلِ جَعْفَرٍ طَعَامًا فَقَدْ أَتَاهُمْ مَا يَشْغَلُهُمْ) رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ وَابْنُ مَاجَهْ
