It is narrated from a Companion (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) once said, "Perhaps you recite (Qur'an) during the recitation of the Imam?" He repeated this question two or three times, so the Companions (may Allah be pleased with them) submitted, "O Messenger of Allah! (peace and blessings be upon him) Indeed, we do so." The Prophet (peace and blessings be upon him) said, "Do not do so, except that one of you wishes to recite Surah Al-Fatihah."
