Umar bin Khattab struck a son of his who used the kunya Abu Isa. Mughira bin Shuba also used the kunya Abu Isa, so Umar said to him, "Is it not enough for you to use the kunya Abu Abdullah?"Mughira replied, "The Messenger of Allah ﷺ himself gave me this kunya."Umar said, "The Messenger of Allah ﷺ has been forgiven his past and future sins, but as for us, we are still among the common folk."So he continued to use the kunya Abu Abdullah until he died.
حدثنا هارون بن زيد بن أبي الزرقاء حدثنا أبي حدثنا هشام بن سعد
أن عمر بن الخطاب رضي الله عنه ضرب ابنا له تكنى أبا عيسى وأن المغيرة بن شعبة تكنى بأبي عيسى فقال له عمر أما يكفيك أن تكنى بأبي عبد الله فقال إن رسول الله ﷺ كناني فقال إن رسول الله ﷺ قد غفر له ما تقدم من ذنبه وما تأخر وإنا في جلجتنا فلم يزل يكنى بأبي عبد الله حتى هلك
[Its isnad is hasan] Bayhaqi transmitted it, 9/310, from the hadith of Abu Dawud through him, and Ibn Kathir graded it hasan in Musnad Farooq, 1/334.
