باب أَجْرِ الْخَازِنِ الأَمِينِ وَالْمَرْأَةِ إِذَا تَصَدَّقَتْ مِنْ بَيْتِ زَوْجِهَا غَيْرَ مُفْسِدَةٍ ب
Sahih Muslim 1024 b

This hadith has been narrated by Mansur with the same chain of transmitters (with this alteration of words):

" from the food of her husband".
وَحَدَّثَنَاهُ ابْنُ أَبِي عُمَرَ، حَدَّثَنَا فُضَيْلُ بْنُ عِيَاضٍ، عَنْ مَنْصُورٍ، بِهَذَا الإِسْنَادِ وَقَالَ ‏ "‏ مِنْ طَعَامِ زَوْجِهَا ‏"‏ ‏.‏
