Musnad Abu Ya'la al-Mawsili 246:17

Zuhayr narrated to us, Hajjaj ibn Muhammad narrated to us, Shu'bah narrated to us, from Sa'd ibn Ibrahim, who said: I heard some of my brothers narrating from my father, from Jubayr ibn Mut'im, that he came to the Prophet (may Allah bless him and grant him peace) regarding the ransom of the polytheists, and he had not yet embraced Islam on that day. He said: I reached him while he was praying the Maghrib prayer, and he was reciting *At-Tur* in it. It was as if my heart had split when I heard the Quran.
