It is narrated from Sayyiduna Jubair bin Mut'im (may Allah be pleased with him) that he came to the service of the Prophet (peace and blessings of Allah be upon him) regarding the ransom of the captives of the Battle of Badr. Until that time, he had not accepted Islam. He says: I entered the Prophet's Mosque while the Prophet (peace and blessings of Allah be upon him) was leading the Maghrib prayer. The Prophet (peace and blessings of Allah be upon him) began reciting Surah At-Tur. When the sound of the Qur'an reached my ears, my heart began to tremble.
