ahmad:2283ʿAffān > Abū ʿAwānah > Abū Bishr > Saʿīd b. Jubayr > Ibn ʿAbbās

[Machine] Indeed, the one you call the "elaborate" is the "firmly established." The Messenger of Allah ﷺ passed away and I was ten years old when I read the "firmly established."  

أحمد:٢٢٨٣حَدَّثَنَا عَفَّانُ حَدَّثَنَا أَبُو عَوَانَةَ حَدَّثَنَا أَبُو بِشْرٍ عَنْ سَعِيدِ بْنِ جُبَيْرٍ قَالَ سَمِعْتُ ابْنَ عَبَّاسٍ قَالَ

إِنَّ الَّذِي تَدْعُونَهُ الْمُفَصَّلَ هُوَ الْمُحْكَمُ تُوُفِّيَ رَسُولُ اللهِ ﷺ وَأَنَا ابْنُ عَشْرِ سِنِينَ وَقَدْ قَرَأْتُ الْمُحْكَمَ
