The Book of Zakat
The virtue of spending and giving charity to relatives, spuses, children and parents, even if they are idolaters
حَدَّثَنَا أَبُو كُرَيْبٍ، مُحَمَّدُ بْنُ الْعَلاَءِ حَدَّثَنَا أَبُو أُسَامَةَ، حَدَّثَنَا هِشَامٌ، عَنْ أَبِيهِ، عَنْ زَيْنَبَ بِنْتِ أَبِي سَلَمَةَ، عَنْ أُمِّ سَلَمَةَ، قَالَتْ 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 .
Umm Salama said: 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 Prophet) said: Yes. For you is the reward for what you spend on them.
