أَخْبَرَنَا مُحَمَّدُ بْنُ سَلَمَةَ، قَالَ حَدَّثَنَا ابْنُ وَهْبٍ، عَنْ عَمْرِو بْنِ الْحَارِثِ، عَنْ أَبِي الأَسْوَدِ، أَنَّهُ سَمِعَ عُرْوَةَ بْنَ الزُّبَيْرِ، يُحَدِّثُ عَنْ زَيْدِ بْنِ ثَابِتٍ، أَنَّهُ قَالَ لِمَرْوَانَ يَا أَبَا عَبْدِ الْمَلِكِ أَتَقْرَأُ فِي الْمَغْرِبِ بِـ { قُلْ هُوَ اللَّهُ أَحَدٌ } وَ { إِنَّا أَعْطَيْنَاكَ الْكَوْثَرَ } قَالَ نَعَمْ . قَالَ فَمَحْلُوفَةٌ لَقَدْ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقْرَأُ فِيهَا بِأَطْوَلِ الطُّولَيَيْنِ { المص } .
Muhammad ibn Salamah informed us: Ibn Wahb narrated to us, from Amr ibn al-Harith, from Abu al-Aswad, who heard Urwah ibn al-Zubair relate from Zayd ibn Thabit that he said to Marwan: Abu Abd al-Malik, do you recite, Say: He is Allah, One, and, Indeed, We have granted you al-Kawthar, in the sunset prayer? He replied, Yes. Zayd said, I swear by Allah, I saw the Messenger of Allah ﷺ recite in it the longer of the two long surahs: Alif Lam Mim Sad.
Translation notes
Alif Lam Mim Sad are the opening letters of Surat al-Araf; the Arabic describes it as the longer of the two long surahs.
