Umm Salamah (May Allah be pleased with her) reported:
I asked Messenger of Allah (ﷺ), "Would I be rewarded for what I spend on Abu Salamah's sons? For I can't let them go here and there (to beg people)." Messenger of Allah (ﷺ) replied, "Spend on them and you will be rewarded for what you spend on them".[Al-Bukhari and Muslim].
