Anas b. Malik reported that Messenger of Allah ﷺ 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). (Using translation from Muslim 2348)

تُوُفِّيَ رَسُولُ اللهِ ﷺ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ وَتُوُفِّيَ أَبُو بَكْرٍ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ وَتُوُفِّيَ عُمَرُ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ

[Machine] The Messenger of Allah ﷺ died at the age of sixty-three. Abu Bakr also died at the age of sixty-three, and Umar died at the age of sixty-three. Today, I am sixty-three years old.

مَاتَ رَسُولُ اللهِ ﷺ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ سَنَةً وَمَاتَ أَبُو بَكْرٍ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ وَمَاتَ عُمَرُ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ وَأَنَا الْيَوْمَ ابْنُ ثَلَاثٍ وَسِتِّينَ

[Machine] He heard Muawiya giving a sermon, saying, "The Messenger of Allah ﷺ passed away when he was sixty-three years old, and Abu Bakr passed away when he was sixty-three, and Umar passed away when he was sixty-three, and I am sixty-three years old."

أَنَّهُ سَمِعَ مُعَاوِيَةَ يَخْطُبُ يَقُولُ مَاتَ رَسُولُ اللهِ ﷺ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ وَأَبُو بَكْرٍ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ وَعُمَرُ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ وَأَنَا ابْنُ ثَلَاثٍ وَسِتِّينَ

[Machine] I heard Muawiyah say, "The Messenger of Allah ﷺ passed away at the age of sixty-three, Abu Bakr passed away at the age of sixty-three, and Umar passed away at the age of sixty-three."

سَمِعْتُ مُعَاوِيَةَ يَقُولُ «مَاتَ رَسُولُ اللهِ ﷺ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ وَمَاتَ أَبُو بَكْرٍ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ وَمَاتَ عُمَرُ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ»
