Narrated 'Abdullah bin Mughaffal:
I saw Allah's Apostle on the day of the Conquest of Mecca over his she-camel, reciting Surat-al-Fath in a vibrant quivering tone. (The sub-narrator, Mu'awiya added, "Were I not afraid that the people may gather around me, I would recite in vibrant quivering tone as he (i.e. 'Abdullah bin Mughaffal) did, imitating Allah's Apostle.")
