I will not give anything today from it to anybody. Then I turned round and saw that the Messenger of Allah ﷺ was smiling (at my words).  

أَصَبْتُ جِرَابًا مِنْ شَحْمٍ يَوْمَ خَيْبَرَ قَالَ فَالْتَزَمْتُهُ فَقُلْتُ لاَ أُعْطِي الْيَوْمَ أَحَدًا مِنْ هَذَا شَيْئًا قَالَ فَالْتَفَتُّ فَإِذَا رَسُولُ اللَّهِ ﷺ مُتَبَسِّمًا  

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 ﷺ and I felt ashamed of my act in his presence.  

فَالْتَفَتُّ فَإِذَا رَسُولُ اللَّهِ ﷺ فَاسْتَحْيَيْتُ مِنْهُ  

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

أَنَّهُ قَالَ جِرَابٌ مِنْ شَحْمٍ وَلَمْ يَذْكُرِ الطَّعَامَ
