I asked the Messenger of Allah ﷺ whether there is a reward for me if I spend on Abu Salama's sons, and I am not going to abandon them in this state (of helplessness) for they are my sons. He (the Holy Prophet) said: Yes. For you is the reward for what you spend on them.

قُلْتُ يَا رَسُولَ اللَّهِ هَلْ لِي أَجْرٌ فِي بَنِي أَبِي سَلَمَةَ أُنْفِقُ عَلَيْهِمْ وَلَسْتُ بِتَارِكَتِهِمْ هَكَذَا وَهَكَذَا إِنَّمَا هُمْ بَنِيَّ فَقَالَ نَعَمْ لَكِ فِيهِمْ أَجْرُ مَا أَنْفَقْتِ عَلَيْهِمْ
