It is narrated from Sayyiduna Ubayy ibn Ka'b (may Allah be pleased with him), he says: I was in the mosque when a man entered and recited (the Qur'an) in a way that I rejected. Then another man entered and he recited contrary to the first person's recitation. We stood up and went to the Noble Prophet (peace and blessings be upon him). I said: O Messenger of Allah! This man recited in a way that I do not know, then this other one entered and he recited contrary to him, and I do not know his recitation either. The Noble Prophet (peace and blessings be upon him) said to both of them: Recite. When they recited, he (peace and blessings be upon him) said: Both of you have recited correctly. Sayyiduna Ubayy (may Allah be pleased with him) says: When the Noble Prophet (peace and blessings be upon him) declared both of them correct, this was very hard on me. When the Noble Prophet (peace and blessings be upon him) saw that this was weighing heavily upon me, he struck his hand on my chest, and I sweated so much that I became drenched, and it felt to me as if I were seeing Allah Almighty out of fear. He (peace and blessings be upon him) said: O Ubayy! My Lord, the Exalted, sent a message to me to recite the Noble Qur'an in one mode of recitation. I requested: Make it easy for my Ummah. So Allah, the Exalted, sent a message to recite in two modes. I again requested: Make it easy for my Ummah. So Allah, the Exalted, sent a message to recite the Qur'an in seven modes of recitation. And as many times as you requested, you may ask from Me. I said: O Allah! Forgive my Ummah, O Allah! Forgive my Ummah. The third supplication I have postponed for the Day when the creation will come to me, until even Ibrahim (peace be upon him).
