Sahih Muslim , Book 32, Hadith 86 (In-Book) ⓘ

It has been narrated on the authority of Abdullah b. Mughaffal who said I found a bag containing fat on the day of the Battle of Khaibar. I caught hold of it and said: I will not give anything today from it to anybody. Then I turned round and saw that the Messenger of Allah was smiling (at my words).

حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا سُلَيْمَانُ، - يَعْنِي ابْنَ الْمُغِيرَةِ - حَدَّثَنَا حُمَيْدُ، بْنُ هِلاَلٍ عَنْ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ، قَالَ أَصَبْتُ جِرَابًا مِنْ شَحْمٍ يَوْمَ خَيْبَرَ - قَالَ - فَالْتَزَمْتُهُ فَقُلْتُ لاَ أُعْطِي الْيَوْمَ أَحَدًا مِنْ هَذَا شَيْئًا - قَالَ - فَالْتَفَتُّ فَإِذَا رَسُولُ اللَّهِ صلى الله عليه وسلم مُتَبَسِّمًا ‏.‏
