Musannaf Ibn Abi Shayba 3:5995

Waki' narrated to us, he said: Shu'bah narrated to us, from Mu'awiyah ibn Qurrah, he said: I heard 'Abdullah ibn Mughaffal saying: The Prophet, may Allah bless him and grant him peace, recited Surah al-Fath while on his riding beast during a journey of his in the year of the Conquest, and he repeated his recitation. Mu'awiyah said: And were it not that I fear that people would gather around me, I would have imitated his recitation for you.
