It is narrated from Hazrat Abdur Rahman bin Abi Laila (may Allah be pleased with him) on the authority of Ubayy bin Ka'b (may Allah be pleased with him) that once I was in the mosque when a man came and started reciting the Qur'an in a way that I did not know. Then another man came and he also recited it in a different manner. We all gathered and went to the service of the Holy Prophet (peace and blessings be upon him) and I said, "O Messenger of Allah! This man came to the mosque and recited the Qur'an in a way that amazed me, then this other one came and he also recited it differently." The Holy Prophet (peace and blessings be upon him) asked both of them to recite, so both of them recited and the Holy Prophet (peace and blessings be upon him) approved of their recitation. On that day, the doubts that came into my mind regarding Islam had never come before. The Holy Prophet (peace and blessings be upon him), seeing this, struck his hand on my chest, which removed all those doubts, and I was overwhelmed and felt as if I was seeing Allah Almighty before me. Then the Holy Prophet (peace and blessings be upon him) said, "Jibreel and Mika'il (peace be upon them) came to me. Hazrat Jibreel (peace be upon him) said, 'Recite the Holy Qur'an on one letter.' I sent a message to my Lord to make it easy for my Ummah. In this way, it continued until it reached seven letters, and Allah sent me a message to recite it on seven letters, and for each time, you may ask Me for one request, I will grant it." So I asked twice for the forgiveness of my Ummah, and I kept the third thing for that day when all creation, even Hazrat Ibrahim (peace be upon him), will come to me.
