Establish the prayer at the decline of the sun till the darkening of the night and the Koran recital at dawn. Surely, the Koran recital at dawn is witnessed. 78 And during a part of the night, pray Tahajjud beyond what is incumbent on you; maybe your Lord will raise you to a position of great glory. 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 say: "Truth has come and falsehood nullified." Verily falsehood is perishable. 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 When We do favors to the human being, he disregards it and turns away from it. When evil afflicts him, he becomes despairing. 83 Say, (O Prophet): "Each one acts according to his own manner. Your Lord knows well who is best-guided to the Right Path." 84
