"The Messenger of Allah ﷺ received Revelation when he was forty years old. So he stayed in Makkah for thirteen years and in Al-Madinah for ten. And he died when he was sixty-three years old."  

أُنْزِلَ عَلَى رَسُولِ اللَّهِ ﷺ وَهُوَ ابْنُ أَرْبَعِينَ فَأَقَامَ بِمَكَّةَ ثَلاَثَ عَشْرَةَ وَبِالْمَدِينَةِ عَشْرًا وَتُوُفِّيَ وَهُوَ ابْنُ ثَلاَثٍ وَسِتِّينَ  

"The Prophet ﷺ died when he was sixty-five years old."  

قُبِضَ النَّبِيُّ ﷺ وَهُوَ ابْنُ خَمْسٍ وَسِتِّينَ وَهَكَذَا حَدَّثَنَا هُوَ يَعْنِي ابْنَ بَشَّارٍ وَرَوَى عَنْهُ مُحَمَّدُ بْنُ إِسْمَاعِيلَ مِثْلَ ذَلِكَ  

"The Messenger of Allah ﷺ was not very tall nor was he [very] short, nor was he pale white, nor was he brown, nor was the wave of his hair completely curly nor straight. Allah sent him at the beginning of his forties and he stayed in Makkah for ten years, and in Al-Madinah for ten years. And Allah took him at the beginning of his sixties, and there were not more than twenty white hairs on his head or in his beard."  

أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ يَقُولُ لَمْ يَكُنْ رَسُولُ اللَّهِ ﷺ بِالطَّوِيلِ الْبَائِنِ وَلاَ بِالْقَصِيرِ الْمُتَرَدِّدِ وَلاَ بِالأَبْيَضِ الأَمْهَقِ وَلاَ بِالآدَمِ وَلَيْسَ بِالْجَعْدِ الْقَطَطِ وَلاَ بِالسَّبِطِ بَعَثَهُ اللَّهُ عَلَى رَأْسِ أَرْبَعِينَ سَنَةً فَأَقَامَ بِمَكَّةَ عَشْرَ سِنِينَ وَبِالْمَدِينَةِ عَشْرَ سِنِينَ وَتَوَفَّاهُ اللَّهُ عَلَى رَأْسِ سِتِّينَ سَنَةً وَلَيْسَ فِي رَأْسِهِ وَلِحْيَتِهِ عِشْرُونَ شَعْرَةً بَيْضَاءَ
