Circumcision at Puberty

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الرَّحِيمِ، أَخْبَرَنَا عَبَّادُ بْنُ مُوسَى، حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ، عَنْ إِسْرَائِيلَ، عَنْ أَبِي إِسْحَاقَ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، قَالَ سُئِلَ ابْنُ عَبَّاسٍ مِثْلُ مَنْ أَنْتَ حِينَ قُبِضَ النَّبِيُّ صلى الله عليه وسلم قَالَ أَنَا يَوْمَئِذٍ مَخْتُونٌ‏.‏ قَالَ وَكَانُوا لاَ يَخْتِنُونَ الرَّجُلَ حَتَّى يُدْرِكَ‏.‏

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. "
