Eat with your right hand. He said: I cannot do that, whereupon he (the Holy Prophet) said: May you not be able to do that. It was vanity that prevented him from doing it, and he could not raise it (the right hand) up to his mouth.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ، عَنْ عِكْرِمَةَ بْنِ عَمَّارٍ، حَدَّثَنِي إِيَاسُ بْنُ سَلَمَةَ بْنِ الأَكْوَعِ، أَنَّ أَبَاهُ، حَدَّثَهُ أَنَّ رَجُلاً أَكَلَ عِنْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم بِشِمَالِهِ فَقَالَ ‏
"‏ كُلْ بِيَمِينِكَ ‏"‏ ‏.‏ قَالَ لاَ أَسْتَطِيعُ قَالَ ‏"‏ لاَ اسْتَطَعْتَ ‏"‏ ‏.‏ مَا مَنَعَهُ إِلاَّ الْكِبْرُ ‏.‏ قَالَ فَمَا رَفَعَهَا إِلَى فِيهِ ‏.‏
