Imam Sajjad (peace be upon him) used to provide food for those who mourned for Imam Husain (peace be upon him)

لَمَّا قُتِلَ الْحُسَيْنُ بْنُ عَلِيٍّ ع لَبِسْنَ نِسَاءَ بَنِي هَاشِمٍ السَّوَادَ وَ الْمُسُوحَ وَ كُنَّ لَا يَشْتَكِينَ مِنْ حَرٍّ وَ لَا بَرْدٍ وَ كَانَ عَلِيُّ بْنُ الْحُسَيْنِ ع يَعْمَلُ لَهُنَّ الطَّعَامَ لِلْمَأْتَمِ.

Imam Husain Ibn Ali (peace be upon him) was martyred, the women of Bani Hashim wore black and coarse woolen clothes; they neither complained about heat nor cold. Imam Ali Ibn al-Husain (peace be upon him) used to feed them during their mourning (beating their chests).

Note

This reflects the deep sorrow and resilience of the women of Bani Hashim during their mourning.
