Keep up prayer from the declining of the sun till the darkness of the night and the morning recitation; surely the morning recitation is witnessed. 78 And as for the night, keep vigil a part of it, as a work of supererogation for thee; it may be that thy Lord will raise thee up to a laudable station. 79 And say: My Lord! Cause me to come in with a firm incoming and to go out with a firm outgoing. And give me from Thy presence a sustaining Power. 80 And say, "Truth has come, and falsehood has departed. Indeed is falsehood, [by nature], ever bound to depart." 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: "Everyone acts in a manner peculiar to himself - and your Sustainer is fully aware as to who has chosen the best path." 84
