Sahl b. Sa'd reported that Mundhir b. Aba Usaid was brought to Allah's Messenger ( صلی اللہ علیہ وسلم ) at the time of his birth Allah's. Apostle ( صلی اللہ علیہ وسلم ) placed him on his thigh and Abfi Usaid kept sitting there. Allah's Apostle ( صلی اللہ علیہ وسلم ) had been occupied with something else before him. Abu Usaid commanded his child to be lifted from the lap of Allah's Messenger ( صلی اللہ علیہ وسلم ) and so he was lifted. When Allah's Messenger ( صلی اللہ علیہ وسلم ) had finished the work he said:
Where is the child? Abd Usaid said: Allah's Messenger, we took him away. He said: What is his name? He said; Allah's Messenger, it is so and so, whereupon he (the Holy Prophet) said: Nay, his name is Mundhir, and named him Mundhir on that day.
