When God’s Messenger once asked Ubayy b. Ka'b how he recited in the course of the prayer and he recited Umm al- Qur’ān (Al-Qur’ān 1) , he said, “By Him in whose hand my soul is, nothing like it has been sent down in the Torah, the Injīl, the Zabūr, or the Qur’ān, and it is seven of the oft-repeated verses and the mighty Qur’ān (Qur’ān, 15:87) which I have been given.”
Tirmidhī transmitted it, and Dārimī transmitted from “nothing like it has been sent down,” but he did not mention Ubayy b. Ka‘b. Tirmidhī said this is a hasan sahīh tradition.
‘Alī reported God’s messenger as saying, “If anyone recites the Qur’ān, learns it by heart, declares what is lawful in it to be lawful and what is unlawful in it to be unlawful, God will bring him into paradise and make him intercessor for ten of his family all of whom have deserved hell.”
Ahmad, Tirmidhī, Ibn Majah and Dārimī transmitted it, Tirmidhī saying that this is a gharīb tradition, and that Hafs b. Sulaīmān the transmitter is not strong, but is declared to be a weak traditionist.
He reported God's messenger as saying, “Learn and recite the Qur’ān, for to one who learns, recites and uses it in prayer at night it is like a bag filled with musk whose fragrance diffuses itself everywhere; and he who learns it and goes to sleep having it within him is like a bag with musk tied up in it.”
