وَحَدَّثَنِي ابْنُ مِنْهَالٍ الضَّرِيرُ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا يُونُسُ بْنُ عُبَيْدٍ، عَنْ عَمَّارٍ، مَوْلَى بَنِي هَاشِمٍ قَالَ سَأَلْتُ ابْنَ عَبَّاسٍ كَمْ أَتَى لِرَسُولِ اللَّهِ صلى الله عليه وسلم يَوْمَ مَاتَ فَقَالَ مَا كُنْتُ أَحْسِبُ مِثْلَكَ مِنْ قَوْمِهِ يَخْفَى عَلَيْهِ ذَاكَ - قَالَ - قُلْتُ إِنِّي قَدْ سَأَلْتُ النَّاسَ فَاخْتَلَفُوا عَلَىَّ فَأَحْبَبْتُ أَنْ أَعْلَمَ قَوْلَكَ فِيهِ . قَالَ أَتَحْسُبُ قَالَ قُلْتُ نَعَمْ . قَالَ أَمْسِكْ أَرْبَعِينَ بُعِثَ لَهَا خَمْسَ عَشْرَةَ بِمَكَّةَ يَأْمَنُ وَيَخَافُ وَعَشْرَ مِنْ مُهَاجَرِهِ إِلَى الْمَدِينَةِ .
Ammar, the freed slave of Banu Hashim, reported:I asked Ibn 'Abbas how old was he when death overtook the Messenger of Allah (ﷺ). He said: I little know that such a thing is not known to a man like you who belong to his people. He said: I asked people about it but they differed with me, and I liked to know your opinion about it. He said: Do you know counting? He said: Yes. He then said: Bear this in mind very well that he was commissioned (as a Prophet) at the age of forty, and he stayed in Mecca for fifteen years; sometime in peace and sometime in dread, and (lived) for ten years after his migration to Medina
