Sahih Muslim , Hadith 1772

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 ‏.‏

This tradition has been transmitted by a different chain of narrators with a different wording, the last in the chain being the same narrator, (i. e. 'Abdullah b. Mughaffal), who said: A bag containing food and fat was thrown to us. I lept forward to catch it. Then I turned round and saw (to my surprise) the Messenger of Allah and I felt ashamed of my act in his presence.

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ الْعَبْدِيُّ، حَدَّثَنَا بَهْزُ بْنُ أَسَدٍ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنِي حُمَيْدُ، بْنُ هِلاَلٍ قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ مُغَفَّلٍ، يَقُولُ رُمِيَ إِلَيْنَا جِرَابٌ فِيهِ طَعَامٌ وَشَحْمٌ يَوْمَ خَيْبَرَفَوَثَبْتُ لآخُذَهُ قَالَ فَالْتَفَتُّ فَإِذَا رَسُولُ اللَّهِ صلى الله عليه وسلم فَاسْتَحْيَيْتُ مِنْهُ ‏.‏

This hadith has been transmitted on the authority of Shu'ba with a slight variation of words.

وَحَدَّثَنَاهُ مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا أَبُو دَاوُدَ، حَدَّثَنَا شُعْبَةُ، بِهَذَا الإِسْنَادِ غَيْرَ أَنَّهُ قَالَ جِرَابٌ مِنْ شَحْمٍ وَلَمْ يَذْكُرِ الطَّعَامَ ‏.‏
