Musnad Abu Ya'la al-Mawsili 246:28

Ishaq narrated to us, al-Nadr narrated to us, Shu'bah narrated to us, from Sa'd ibn Ibrahim, who said: Some of my brothers informed me, from Jubayr ibn Mut'im, that he came to the Prophet, may Allah bless him and grant him peace, regarding the ransom of the captives of the polytheists. He said: So I came to the Prophet, may Allah bless him and grant him peace, while he was praying the Maghrib prayer, and he recited in it "al-Tur." It was as if my heart had split when I heard the Qur'an.
