Iyas bin Abi Salamah said: My father narrated a hadith to me and said: The Messenger of Allah (peace be upon him) saw Busar bin Ra’i al-‘Ir eating with his left hand. The Prophet (peace be upon him) said: “Eat with your right hand.” He replied: “I cannot.” The Prophet (peace be upon him) said: “May you never be able to (if you are lying),” and the narrator said: After that, his right hand could never reach his mouth.
