question #3 Sahih al-Bukhari 6299, Book 79, Hadith 71 : What can be inferred about Ibn ‘Abbas’s age at the time of the Prophet’s death based on his circumcision status?

Ibn ‘Abbas was asked, “How old were you when
the Prophet (ﷺ) 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. ”
