Sahih al-Bukhari, Volume 9, Book 93, Hadith 631 (USC-MSA) ⓘ
Narrated Shu`ba: Mu'awiya bin Qurra reported that `Abdullah bin Al-Maghaffal Al-Muzani said, "I saw Allah's Messenger on the day of the Conquest of Mecca, riding his she-camel and reciting Surat-al-Fath (48) or part of Surat-al-Fath. He recited it in a vibrating and pleasant voice. Then Mu'awiya recited as `Abdullah bin Mughaffal had done and said, "Were I not afraid that the people would crowd around me, I would surely recite in a vibrating pleasant voice as Ibn Mughaffal did, imitating the Prophet." I asked Muawiya, "How did he recite in that tone?" He said thrice, "A, A, A."
حَدَّثَنَا أَحْمَدُ بْنُ أَبِي سُرَيْجٍ، أَخْبَرَنَا شَبَابَةُ، حَدَّثَنَا شُعْبَةُ، عَنْ مُعَاوِيَةَ بْنِ قُرَّةَ، عَنْ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ الْمُزَنِيِّ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَوْمَ الْفَتْحِ عَلَى نَاقَةٍ لَهُ يَقْرَأُ سُورَةَ الْفَتْحِ، أَوْ مِنْ سُورَةِ الْفَتْحِ ـ قَالَ ـ فَرَجَّعَ فِيهَا ـ قَالَ ـ ثُمَّ قَرَأَ مُعَاوِيَةُ يَحْكِي قِرَاءَةَ ابْنِ مُغَفَّلٍ وَقَالَ " لَوْلاَ أَنْ يَجْتَمِعَ النَّاسُ عَلَيْكُمْ لَرَجَّعْتُ كَمَا رَجَّعَ ابْنُ مُغَفَّلٍ " . يَحْكِي النَّبِيَّ صلى الله عليه وسلم فَقُلْتُ لِمُعَاوِيَةَ كَيْفَ كَانَ تَرْجِيعُهُ قَالَ آ آ آ ثَلاَثَ مَرَّاتٍ.

And Ibn 'Abbas narrated: Abu Sufyan bin Harb told me that Heraclius called for his translator and then asked for the letter of the Prophet, and the former read it (thus): "In the Name of Allah, the Most Gracious, the Merciful. (This letter is) from Muhammad bin 'Abdullah, to Heraclius. "...O people of the Scripture (Jews and Christians): Come to a word that is just between us and you that we worship none but Allah..." (V.3:64)
وَقَالَ ابْنُ عَبَّاسٍ أَخْبَرَنِي أَبُو سُفْيَانَ بْنُ حَرْبٍ، أَنَّ هِرَقْلَ، دَعَا تَرْجُمَانَهُ، ثُمَّ دَعَا بِكِتَابِ النَّبِيِّ صلى الله عليه وسلم فَقَرَأَهُ " بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ مِنْ مُحَمَّدٍ عَبْدِ اللَّهِ وَرَسُولِهِ إِلَى هِرَقْلَ، وَ{يَا أَهْلَ الْكِتَابِ تَعَالَوْا إِلَى كَلِمَةٍ سَوَاءٍ بَيْنَنَا وَبَيْنَكُمْ }" الآيَةَ.
