(2) باب الإِحْسَانِ إِلَى الأَرْمَلَةِ وَالْمِسْكِينِ وَالْيَتِيمِ
Abu Huraira reported that Allah's Messenger (ﷺ) said:
One who makes efforts (for earning to be spent) on a widow and the destitute is like a striver in the cause of Allah, and I think he also said: He is like one who constantly stands for prayer and observes fast without breaking it.
