It is reported that there used to be poor people in Al-Madînah who didn’t know where they were getting their food from. When ‘Alî b. Husayn passed away, they started missing what they used to be given at night.
Abû Hamzah Al-Thumâlî narrates that ‘Alî b. Husayn used to carry bread on his back in the darkness of the night and follow the poor people (to give it to them). He used to say, “Charity in the darkness of the night extinguishes the Lords anger.”
‘Amr b. Thâbit reports that when ‘Alî b. Husayn died, they found marks on his back from the sacks of provisions he used to carry at night to the houses of the widows.
Shaybah b. Nu’âmah narrates that when ‘Alî b. Husayn died they found out that he used to provide for a hundred (poor) families.
