Iyas bin Salama reported,

The Prophet ﷺ saw a man eating with his left hand and said, "Eat with your right."The man replied, "I cannot."The Prophet ﷺ said, "May you never be able to."Nothing prevented him from doing so except pride, and after that he could never raise his hand to his mouth again.

Ahmad 16530
