Jubayr bin Nufayr narrates that the Messenger of Allah (peace and blessings be upon him) said: "Allah Almighty has not granted His servant permission for anything as much as for (praying) two rak'ahs or more; and as long as the servant is in prayer, righteousness keeps scattering over his head; and the servant does not present anything to Allah, the Mighty and Majestic, better than that which came forth from Him," meaning the Qur'an.
