Arabic
وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «اخْتَتَنَ إِبْرَاهِيمُ النَّبِيُّ وَهُوَ ابْنُ ثَمَانِينَ سَنَةً بِالْقَدُومِ» . مُتَّفق عَلَيْهِ
English translation
Abu Huraira reported God's messenger as saying, "Abraham the prophet circumcised himself with an axe[*] when he was eighty years old." *The Arabic is bil-qadum which has the meaning above. Another reading is bil-qaddum which is said to mean at al-Qaddum' (a village in Syria); but this version with the doubled letter is not considered correct. (Bukhari and Muslim.)
