546. hadíth
وَ أَوْصَى أَبُو جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ بِثَمَانِمِائَةِ دِرْهَمٍ لِمَأْتَمِهِ وَ كَانَ يَرَى ذَلِكَ لِلسُّنَّةِ لِأَنَّ رَسُولَ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ قَالَ «اِتَّخِذُوا لآِلِ جَعْفَرِ بْنِ أَبِي طَالِبٍ طَعَاماً فَقَدْ شُغِلُوا.
Imam al-Baqir (a.s) made a will specifying 800 dirhams to be used for his mourning gathering (ma'tam), as he saw this as part of the tradition (sunnah). This was because the Messenger of Allah (saws) said: "Prepare food for the family of Ja'far ibn Abi Talib, for they are preoccupied [by their loss]."
