Sahl bin Sa’d (may Allah be pleased with him) narrated that Mundhir bin Abi Usaid (may Allah be pleased with him) was born, so he was brought to the Prophet Muhammad (peace and blessings be upon him). The Prophet (peace be upon him) placed the child on his thigh. Abu Usaid (may Allah be pleased with him) was sitting. The Prophet (peace be upon him) became occupied with something in front of him (and his attention was diverted from the child). Abu Usaid (may Allah be pleased with him) ordered regarding the child, and he was lifted from the Prophet’s thigh. Then, when the Prophet (peace be upon him) turned his attention back, he said:“Where is the child?”Abu Usaid (may Allah be pleased with him) replied,“O Messenger of Allah! We have sent him home.”The Prophet (peace be upon him) asked,“What is his name?”He replied,“So-and-so.”The Prophet (peace be upon him) said,“Rather, his name is Mundhir.”Thus, on that very day, the Prophet (peace be upon him) named him Mundhir.
