باب فَضْلِ النَّفَقَةِ وَالصَّدَقَةِ عَلَى الْأَقْرَبِينَ وَالزَّوْجِ وَالْأَوْلَادِ وَالْوَالِدَيْنِ وَلَوْ كَانُوا مُشْرِكِينَ
Sahih Muslim 1000 a

Zainab, the wife of 'Abdullah (b. Mas'ud ), reported that the Messenger of Allah (ﷺ) said:

0 women, give sadaqa even though it be some of your jewellery. She returned to 'Abdullah and said: You are a person with empty hands, whereas the Messenger of Allah (ﷺ) has commanded us to give sadaqa, so better go to him and ask and if this will suffice for me; otherwise I shall give it to someone else. 'Abdullah said to me (his wife): You better go yourself. So I went and there was another woman of the Ansar at the door of the Messenger of Allah (ﷺ) having the same porpose as I had. Now Allah's Messenger (ﷺ) was invested with awe (so we did not like to knock). Then Bilal came out and we said to him: Go to the Messenger of Allah (ﷺ) and inform him that there are two women at the door asking him whether it will serve them to give sadaqa to their spouses and to orphans who are under their charge, but do not inform him who we are. Bilal went to the Messenger of Allah (ﷺ) and asked him (what these women had instructed him to ask). The Messenger of Allah (ﷺ) asked him who these women were. He (Bilal) said: They are women from Ansar and Zainab. Upon this the Messenger of Allah (ﷺ) said: Which of the Zainabs? He said: The wife of 'Abdullah. The Messenger of Allah (ﷺ) said: There are two rewards for them, the reward of kinship and the reward of Sadaqa.
حَدَّثَنَا حَسَنُ بْنُ الرَّبِيعِ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنِ الأَعْمَشِ، عَنْ أَبِي وَائِلٍ، عَنْ عَمْرِو بْنِ الْحَارِثِ، عَنْ زَيْنَبَ، امْرَأَةِ عَبْدِ اللَّهِ قَالَتْ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ تَصَدَّقْنَ يَا مَعْشَرَ النِّسَاءِ وَلَوْ مِنْ حُلِيِّكُنَّ ‏"‏ ‏.‏ قَالَتْ فَرَجَعْتُ إِلَى عَبْدِ اللَّهِ فَقُلْتُ إِنَّكَ رَجُلٌ خَفِيفُ ذَاتِ الْيَدِ وَإِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَدْ أَمَرَنَا بِالصَّدَقَةِ فَأْتِهِ فَاسْأَلْهُ فَإِنْ كَانَ ذَلِكَ يَجْزِي عَنِّي وَإِلاَّ صَرَفْتُهَا إِلَى غَيْرِكُمْ ‏.‏ قَالَتْ فَقَالَ لِي عَبْدُ اللَّهِ بَلِ ائْتِيهِ أَنْتِ ‏.‏ قَالَتْ فَانْطَلَقْتُ فَإِذَا امْرَأَةٌ مِنَ الأَنْصَارِ بِبَابِ رَسُولِ اللَّهِ صلى الله عليه وسلم حَاجَتِي حَاجَتُهَا - قَالَتْ - وَكَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم قَدْ أُلْقِيَتْ عَلَيْهِ الْمَهَابَةُ - قَالَتْ - فَخَرَجَ عَلَيْنَا بِلاَلٌ فَقُلْنَا لَهُ ائْتِ رَسُولَ اللَّهِ صلى الله عليه وسلم فَأَخْبِرْهُ أَنَّ امْرَأَتَيْنِ بِالْبَابِ تَسْأَلاَنِكَ أَتَجْزِي الصَّدَقَةُ عَنْهُمَا عَلَى أَزْوَاجِهِمَا وَعَلَى أَيْتَامٍ فِي حُجُورِهِمَا وَلاَ تُخْبِرْهُ مَنْ نَحْنُ - قَالَتْ - فَدَخَلَ بِلاَلٌ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَسَأَلَهُ فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَنْ هُمَا ‏"‏ ‏.‏ فَقَالَ امْرَأَةٌ مِنَ الأَنْصَارِ وَزَيْنَبُ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَىُّ الزَّيَانِبِ ‏"‏ ‏.‏ قَالَ امْرَأَةُ عَبْدِ اللَّهِ ‏.‏ فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ لَهُمَا أَجْرَانِ أَجْرُ الْقَرَابَةِ وَأَجْرُ الصَّدَقَةِ ‏"‏ ‏.‏
