It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) with reference to Ubayy bin Ka'b (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: "Shall I not teach you a Surah the like of which is not found in the Torah, the Psalms, the Gospel, nor even in the Qur'an itself?" I said, "Why not?" The Holy Prophet (peace and blessings be upon him) said, "I hope that you will not leave through this door until you have learned it." Then the Holy Prophet (peace and blessings be upon him) stood up and I stood up with him. The Holy Prophet (peace and blessings be upon him) took my hand and began to talk to me, and as we walked, we reached near the door. I reminded the Holy Prophet (peace and blessings be upon him) and said, "O Messenger of Allah! Please tell me the Surah about which you spoke to me." The Holy Prophet (peace and blessings be upon him) said, "When you stand to pray, what do you recite?" He recited Surah Al-Fatiha. The Holy Prophet (peace and blessings be upon him) said, "That is the Surah. That is the Seven Oft-Repeated (verses), and that is the Great Qur'an which has been given to me."
