that Messenger of Allah ﷺ said "The Prophet) Abraham circumcised himself after he had passed the age of eighty years and he circumcised himself with an adze."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «اخْتَتَنَ إِبْرَاهِيمُ بَعْدَ ثَمَانِينَ سَنَةً وَاخْتَتَنَ بِالْقَدُومِ مُخَفَّفَةً۔» حَدَّثَنَا قُتَيْبَةُ حَدَّثَنَا الْمُغِيرَةُ عَنْ أَبِي الزِّنَادِ وَقَالَ بِالْقَدُّومِ وَهُوَ مَوْضِعٌ مُشَدَّدٌ
