Musannaf Ibn Abi Shaybah 33904 — What Allah the Exalted gave Muhammad

Sayyiduna Ubayy (may Allah be pleased with him) said that the Prophet (peace and blessings be upon him) said to him: O Ubayy, my Lord revealed to me that I should recite the Qur'an in one harf. I said: Make it easy for my Ummah. Allah said: Recite the Qur'an in seven ahruf; and for each time, you have a supplication which you may ask of Me. He said: O Allah, forgive my Ummah; O Allah, forgive my Ummah; and I have deferred the third supplication to the day on which the creation will turn to me in hope, even Ibrahim (peace be upon him).
