In-book no 5223حَدَّثَنَا أَبُو كُرَيْبٍ، مُحَمَّدُ بْنُ الْعَلاَءِ حَدَّثَنَا وَكِيعٌ، عَنْ فُضَيْلِ بْنِ غَزْوَانَ، عَنْ أَبِي، حَازِمٍ عَنْ أَبِي هُرَيْرَةَ، . أَنَّ رَجُلاً، مِنَ الأَنْصَارِ بَاتَ بِهِ ضَيْفٌ فَلَمْ يَكُنْ عِنْدَهُ إِلاَّ قُوتُهُ وَقُوتُ صِبْيَانِهِ فَقَالَ لاِمْرَأَتِهِ نَوِّمِي الصِّبْيَةَ وَأَطْفِئِي السِّرَاجَ وَقَرِّبِي لِلضَّيْفِ مَا عِنْدَكِ - قَالَ - فَنَزَلَتْ هَذِهِ الآيَةُ { وَيُؤْثِرُونَ عَلَى أَنْفُسِهِمْ وَلَوْ كَانَ بِهِمْ خَصَاصَةٌ}
Abu Huraira reported that a guest spent the night with a person from the Ansar who had nothing with him but food (sufficient) for his own self and his children. He said to his wife: (Lull) the children to sleep, and put out the lamp, and serve the guest with what you have with you. It was on this occasion that this verse was revealed:" Those who prefer the needy to their own selves in spite of the fact that they are themselves in pressing need" (Lix. 9).
