A man was eating in the presence of the Messenger of Allah ﷺ with his left hand, so he said, "Eat with your right hand."The man replied, "I am not able to."The Prophet ﷺ said, "May you never be able to." Nothing prevented him from doing so except arrogance. After that, he could never raise his right hand to his mouth again.
أن رجلا أكل عند رسول الله ﷺ بشماله، فقال: كل بيمينك، قال: لا أستطيع، قال: لا استطعت، ما منعه إلا الكبر، قال: فما رفعها إلى فيه.
Narrated by Muslim in the Book of Drinks (2021), from Abu Bakr bin Abu Shayba, who said, Zayd bin Hubab related to us, from Ikrima bin Ammar, who said, Iyas bin Salama bin Akwa related to me, that his father related to him, and he mentioned the hadith.This man's name was Busr bin Rai al-Eer, as reported by Ahmad (16499), from Bahz bin Assad Ammi, who said, Ikrima bin Ammar Yamami related to us, who said, Iyas bin Salama bin Akwa related to us, that his father related to him, saying, I heard the Messenger of Allah ﷺ say to a man called Busr bin Rai al-Eer, when he saw him eating with his left hand, "Eat with your right hand." The man said, "I cannot." So he said, "May you never be able to." The narrator said, After that his right hand never again reached his mouth.Abu Nadr said in his version of the hadith, Ibn Rai al-Eer was from Ashja. Abu Nadr is Hashim bin Qasim, and from him Abd bin Humayd related this account in al-Muntakhab (388), where he said of him, He is called Busr bin Rai al-Eer.Ibn Abdul-Barr did not mention Busr bin Rai al-Eer among the companions in al-Istiab, but Ibn Manda and Abu Naeem both mentioned him among the companions.His statement, "I cannot," was said out of arrogance, as the story indicates, and the Prophet's ﷺ statement, "May you never be able to," was a supplication against him, and it came to pass.
