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. (Using translation from Muslim 1001a)
قُلْتُ يَا رَسُولَ اللهِ هَلْ لِي مِنْ أَجْرٍ فِي بَنِي أَبِي سَلَمَةَ أَنْ أُنْفِقَ عَلَيْهِمْ وَلَسْتُ بِتَارِكَتِهِمْ هَكَذَا وَهَكَذَا وَهَكَذَا إِنَّمَا هُمْ بَنِيَّ؟ قَالَ نَعَمْ لَكَفِيهِمْ أَجْرٌ مَا أَنْفَقْتِ عَلَيْهِمْ
