حَدَّثَنَا يَحْيَى بْنُ قُزَعَةَ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ الْفِطْرَةُ خَمْسٌ الْخِتَانُ، وَالاِسْتِحْدَادُ، وَنَتْفُ الإِبْطِ، وَقَصُّ الشَّارِبِ، وَتَقْلِيمُ الأَظْفَارِ ‏"‏‏.‏
Translation
Narrated Said bin Jubair

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. "
