Riyad as-Salihin 741
Salamah bin Al-Akwa' (May Allah be pleased with him) reported on the authority of his father:
A man ate with his left hand in the presence of Messenger of Allah (ﷺ), whereupon he said, "Eat with your right hand." The man said: "I cannot do that." Thereupon he (the Prophet (ﷺ)) 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 afterwards.

[Muslim].

وعن سلمةَ بن الأَكْوَع أنَّ رَجُلاً أَكَلَ عِنْدَ رَسُولِ الله بِشِمَالِهِ ، فَقَالَ : « كُلْ بِيَمِينِكَ » قَالَ : لا أسْتَطِيعُ . قَالَ : « لا اسْتَطَعْتَ » ! مَا مَنَعَهُ إِلا الكِبْرُ ! فَمَا رَفَعَهَا إِلَى فِيهِ . ((رواه مسلم))
