حَدَّثَنَا رَوْحٌ حَدَّثَنَا هِشَامٌ حَدَّثَنَا عِكْرِمَةُ عَنِ ابْنِ عَبَّاسٍ قَالَ بُعِثَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِأَرْبَعِينَ سَنَةً فَمَكَثَ بِمَكَّةَ ثَلَاثَ عَشْرَةَ سَنَةً يُوحَى إِلَيْهِ ثُمَّ أُمِرَ بِالْهِجْرَةِ فَهَاجَرَ عَشْرَ سِنِينَ فَمَاتَ وَهُوَ ابْنُ ثَلَاثٍ وَسِتِّينَ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
مسند امام احمد بن حنبل · Hadith 3517
It was narrated that Ibn 'Abbas (RA) said: The Messenger of Allah (PBUH) was sent when he was forty years old. He stayed in Makkah for thirteen years, receiving Revelation, then he was commanded to migrate, so he migrated (and stayed in Madinah) for ten years, then he died when he was sixty-three years old.
