Sahih al-Bukhari 3902
Narrated Ibn `Abbas:
Allah's Messenger (ﷺ) started receiving the Divine Inspiration at the age of forty. Then he stayed in Mecca 
for thirteen years, receiving the Divine Revelation. Then he was ordered to migrate and he lived as an 
Emigrant for ten years and then died at the age of sixty-three (years).
حَدَّثَنَا مَطَرُ بْنُ الْفَضْلِ، حَدَّثَنَا رَوْحٌ، حَدَّثَنَا هِشَامٌ، حَدَّثَنَا عِكْرِمَةُ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ بُعِثَ رَسُولُ اللَّهِ صلى الله عليه وسلم لأَرْبَعِينَ سَنَةً، فَمَكُثَ بِمَكَّةَ ثَلاَثَ عَشْرَةَ سَنَةً يُوحَى إِلَيْهِ، ثُمَّ أُمِرَ بِالْهِجْرَةِ فَهَاجَرَ عَشْرَ سِنِينَ، وَمَاتَ وَهُوَ ابْنُ ثَلاَثٍ وَسِتِّينَ‏.‏
