Sahih al-Bukhari 7540
Narrated Shu`ba:
Mu'awiya bin Qurra reported that `Abdullah bin Al-Maghaffal Al-Muzani said, "I saw Allah's Messenger (ﷺ) 
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.‏
