Establish prayer at the decline of the sun [from its meridian] until the darkness of the night and [also] the Qur'an of dawn. Indeed, the recitation of dawn is ever witnessed. 78 And some part of the night awake for it, a largess for thee. It may be that thy Lord will raise thee to a praised estate. 79 And say: 'My Lord, lead me in with a just ingoing, and lead me out with a just outgoing; grant me authority from Thee, to help me.' 80 And proclaim: "The Truth has come, and falsehood has vanished. Surely falsehood is ever bound to vanish." 81 We reveal the Quran which is a cure and mercy for the believers but does nothing for the unjust except to lead them to perdition. 82 Yet when We bestow favors upon mankind he turns his back and withdraws to one side. But when evil befalls him, he despairs. 83 Say: 'Every man works according to his own manner; but your Lord knows very well what man is best guided as to the way.' 84
