(the daughter of Um Salama) My mother said, "O Messenger of Allah ﷺ! Shall I receive a reward if I spend for the sustenance of Abu Salama's offspring, and in fact they are also my sons?" The Prophet ﷺ replied, "Spend on them and you will get a reward for what you spend on them."
قُلْتُ يَا رَسُولَ اللَّهِ أَلِيَ أَجْرٌ أَنْ أُنْفِقَ عَلَى بَنِي أَبِي سَلَمَةَ إِنَّمَا هُمْ بَنِيَّ فَقَالَ أَنْفِقِي عَلَيْهِمْ فَلَكِ أَجْرُ مَا أَنْفَقْتِ عَلَيْهِمْ
