951/1250 (Authentic chain, mawquf and maqtu‘, and authentically attributed to him as marfu‘) from Abu Huraira who said: "Ibrahim, peace be upon him, was circumcised when he was one hundred and twenty years old, then lived after that for eighty years. Sa‘id [بن المسيب] said: 'Ibrahim was the first to be circumcised, the first to host guests, the first to trim the mustache, the first to cut the nails, and the first to have gray hair. He said: O Lord! What is this? He said: Dignity. He said: O Lord, increase me in dignity.'"

952/1251 (Authentic chain, mawquf and mursal) from Al-Hasan [هو البصري] who said: "Are you not amazed at this? – meaning: Malik ibn Al-Mundhir – he went to some elders from the people of (Kaskar) who had accepted Islam, so he examined them and ordered that they be circumcised, and it was winter, and I was informed that some of them died. Indeed, the Roman and the Abyssinian accepted Islam with the Messenger of Allah, peace and blessings be upon him, and nothing was examined about them." (1).

953/1252 (Authentic chain, mawquf or maqtu‘) from Ibn Shihab who said: "When a man accepted Islam, he was ordered to be circumcised even if he was an adult."
