Establish thou the prayer from the declination of the sun to the darkening of the night, and the recitation at the dawn; verily the recitation at the dawn is ever borne witness to. 78 As for the night there is a voluntary deed for you to keep vigil in part it. Perhaps your Lord will raise you to a praiseworthy station. 79 And say, "My Lord, cause me to enter a sound entrance and to exit a sound exit and grant me from Yourself a supporting authority." 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 When We bestow a favour upon a person, he turns his back and draws aside; and when evil afflicts him he gives himself up to despair. 83 Say: "Everyone acts according to his own disposition: But your Lord knows best who it is that is best guided on the Way." 84
