Mu'awiya b. Qurra is reported to have heard 'Abdullah b. Mughaffal as saying:I saw the Messenger of Allah (ﷺ) reciting Surah Fath on his camel on the day of the Conquest of Mecca. He (the narrator) said: Ibn Mughaffal recited it and repeated it. Mu'awiya said: Had there been (no crowed of) people, I would have given a practical demonstration of that which Ibn Mughaffal had mentioned from the Messenger of Allah (ﷺ)
