Sahih Muslim , Hadith 2348 ⓘ

Anas b. Malik reported that Allah's Messenger died when he was sixty-three years old, and so was the case with Abu Bakr, and so was the case with Umar who was also sixty-three (when he died).

حَدَّثَنِي أَبُو غَسَّانَ الرَّازِيُّ، مُحَمَّدُ بْنُ عَمْرٍو حَدَّثَنَا حَكَّامُ بْنُ سَلْمٍ، حَدَّثَنَا عُثْمَانُ، بْنُ زَائِدَةَ عَنِ الزُّبَيْرِ بْنِ عَدِيٍّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قُبِضَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَهُوَ ابْنُ ثَلاَثٍ وَسِتِّينَ وَأَبُو بَكْرٍ وَهُوَ ابْنُ ثَلاَثٍ وَسِتِّينَ وَعُمَرُ وَهُوَ ابْنُ ثَلاَثٍ وَسِتِّينَ ‏.‏
