question #1 Sahih Muslim 1001a, Book 12, Hadith 57 : What is the significance of spending on one’s stepchildren in Islam?

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.
