Sahl said, "Al-Mundhir ibn Abi Usayd was brought to the Prophet (ﷺ) when he was born and the Prophet placed him on his thigh while Abu Usayd was seated near him. The Prophet (ﷺ) was busy with something in front of him, so Abu Usayd told someone to take his son from the Prophet's leg. When the Prophet (ﷺ) became aware of it, he asked, 'Where is the child?' Abu Usayd replied, 'We sent him home.' The Prophet asked, 'What is his name?' He replied, 'Such-and-such.' The Prophet said, 'No, rather his name is al-Mundhir.' So we called him al-Mundhir from that day."
