[Machine] He heard Marwan reciting "Say, He is Allah, the One" and "Indeed, We have granted you, [O Muhammad], al-Kawthar." So Zaid said, "By Allah, I swear I have seen the Messenger of Allah ﷺ reciting in it (the Qur'an) with the longest of the two long chapters."  

ابن حبّان:١٨٣٦ – أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ سَلْمٍ قَالَ حَدَّثَنَا حَرْمَلَةُ بْنُ يَحْيَى قَالَ حَدَّثَنَا ابْنُ وَهْبٍ قَالَ أَخْبَرَنِي عَمْرُو بْنُ الْحَارِثِ عَنْ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ أَنَّهُ سَمِعَ عُرْوَةَ بْنَ الزُّبَيْرِ يُحَدِّثُ عَنْ زَيْدِ بْنِ ثَابِتٍ

أَنَّهُ سَمِعَ مَرْوَانَ يَقْرَأُ بِ قُلْ هُوَ اللَّهُ أَحَدٌ وَإِنَّا أَعْطَيْنَاكَ الْكَوْثَرَ فَقَالَ زَيْدٌ «فَحَلَفْتُ بِاللَّهِ لَقَدْ رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَقْرَأُ فِيهَا بِأَطْوَلِ الطَّوِيلَتَيْنِ »
