Establish regular prayers - at the sun's decline till the darkness of the night, and the morning prayer and reading: for the prayer and reading in the morning carry their testimony. 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! make me to enter a goodly entering, and cause me to go forth a goodly going forth, and grant me from near Thee power to assist (me). 80 Say, 'Truth has come and falsehood has been banished; it is doomed to banishment.'" 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: Every one acts according to his manner; but your Lord best knows who is best guided in the path. 84
