Narrated Umar ibn al-Khattab: Zayd ibn Aslam quoted his father as saying: Umar ibn al-Khattab (Allah be pleased with him) struck one of his sons who was given the kunyah Abu Isa, and al-Mughirah ibn Shubah had the kunyah Abu Isa. Umar said to him: Is it not sufficient for you that you are called by the kunyah Abu Abdullah? He replied: The Messenger of Allah صلی اللہ علیہ وسلم gave me this kunyah. Thereupon he said: The Messenger of Allah صلی اللہ علیہ وسلم was forgiven all his sins, past and those followed. But we are among the people similar to us. Henceforth he was called by the kunyah Abu Abdullah until he died.
