Musa bin Ali (may Allah have mercy on him) narrates from his father that Ibrahim (peace be upon him) was commanded to be circumcised at the age of 80, so he did it with an adze. The pain became severe, so he supplicated to Allah, and Allah Almighty said: "You hastened before (We) gave the command about the instrument." Ibrahim (peace be upon him) replied: "O Allah! I did not like to delay Your command."
He said: Isma'il (peace be upon him) was circumcised at the age of 13 and Ishaq (peace be upon him) at the age of 7 days.
