Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) led his companions in prayer. When he completed the prayer, he turned towards the people and said: Do you recite (Qur'an) behind your Imam when the Imam is reciting? The people remained silent. The Prophet (peace and blessings be upon him) repeated this statement three times, then one person said, or perhaps the people said: We do so. The Prophet (peace and blessings be upon him) said: Do not do so. Each one of you should recite Surah Al-Fatihah in his heart. The wording of the narration: "Do not do so"—these are words of prohibition, but what is meant is to give a new ruling from the beginning, because the Arabs often use such expressions in their idioms.
