Hadith: O Messenger of Allah, would I be rewarded for Abu Salāmah's children that I spend on them so as not to leave them like this and like that, while they are my children? He said: Yes, you will be rewarded for what you spend on them

عن أم سلمة رضي الله عنها ، قالت: قلت: يا رسول الله، هل لي أجرٌ في بني أبي سلمة أن أُنْفِقَ عليهم، ولستُ بتاركتهم هكذا وهكذا إنما هم بَنِيَّ؟ فقال: «نعم، لك أجرُ ما أنفقتِ عليهم».
[صحيح] - [متفق عليه]

Umm Salāmah (may Allah be pleased with her) reported: I said: "O Messenger of Allah, would I be rewarded for Abu Salāmah's children that I spend on them so as not to leave them like this and like that, while they are my children?" He said: "Yes, you will be rewarded for what you spend on them."
[Authentic hadith] - [Narrated by Bukhari & Muslim]

Explanation

Umm Salāmah (may Allah be pleased with her) asked the Prophet (may Allah's peace and blessings be upon him) if she would get a reward in the Hereafter for providing for her children from Abu Salāmah, thus not letting them spread in pursuit of sustenance, or she would not be rewarded because she does that out of compassion for her children. The Prophet (may Allah's peace and blessings be upon him) told her that she would be rewarded.
