Bukhari :: Book 8 :: Volume 74 :: Hadith 313
Narrated Abu Huraira:
Allah's Apostle said "The Prophet) Abraham circumcised himself after he had passed the age of eighty years and he circumcised himself with an adze."
Narrated Said bin Jubair: Ibn 'Abbas was asked, "How old were you when the Prophet died?" He replied. "At that time I had been circumcised." At that time, people did not circumcise the boys till they attained the age of puberty. Sa'id bin Jubair said, "Ibn 'Abbas said, 'When the Prophet died, I had already been circumcised. "
