Sahih Muslim , Book 43, Hadith 153 (In-Book) ⓘ

'Amr reported: I said to 'Urwa: How long did Allah's Apostle stay in Mecca? He said: For ten years. I said: Ibn Abbas says it is some years above ten. He ('Urwa) sought forgiveness for him and said: His statement is based on the verse of a poet.

وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، قَالَ قُلْتُ لِعُرْوَةَ كَمْ لَبِثَ النَّبِيُّ صلى الله عليه وسلم بِمَكَّةَ قَالَ عَشْرًا ‏.‏ قُلْتُ فَإِنَّ ابْنَ عَبَّاسٍ يَقُولُ بِضْعَ عَشْرَةَ ‏.‏ قَالَ فَغَفَّرَهُ وَقَالَ إِنَّمَا أَخَذَهُ مِنْ قَوْلِ الشَّاعِرِ ‏.‏
