Sunan Ibn Majah, Book 8, Hadith 53 (In-Book) ⓘ
It was narrated that: Umm Salamah said: “The Messenger of Allah enjoined charity upon us. Zainab, the wife of Abdullah said: 'Will it be accepted as charity on my part if I give charity to my husband who is poor, and to the children of a brother of mine who are orphans, spending such and such on them, and in all circumstances?' He said: 'Yes.'”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَحْيَى بْنُ آدَمَ، حَدَّثَنَا حَفْصُ بْنُ غِيَاثٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ زَيْنَبَ بِنْتِ أُمِّ سَلَمَةَ، عَنْ أُمِّ سَلَمَةَ، قَالَتْ أَمَرَنَا رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ بِالصَّدَقَةِ . فَقَالَتْ زَيْنَبُ امْرَأَةُ عَبْدِ اللَّهِ أَيُجْزِينِي مِنَ الصَّدَقَةِ أَنْ أَتَصَدَّقَ عَلَى زَوْجِي وَهُوَ فَقِيرٌ وَبَنِي أَخٍ لِي أَيْتَامٍ وَأَنَا أُنْفِقُ عَلَيْهِمْ هَكَذَا وَهَكَذَا وَعَلَى كُلِّ حَالٍ قَالَ " نَعَمْ " . قَالَ وَكَانَتْ صَنَاعَ الْيَدَيْنِ .
