Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "The prayer is not valid in which Surah Al-Fatihah is not recited." The narrator says (I said to Sayyiduna Abu Hurairah, may Allah be pleased with him): If I am behind the Imam, so he took my hand and said: You should recite it in your heart.
