Say your prayers from the decline of the sun, until nightfall; and at dawn -- the recitation at dawn is indeed witnessed. 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 Say: 'Lord, grant me an entrance of sincerity and an exit of sincerity, and give me from Yours a victorious power' 80 And say: "Truth has (now) arrived, and Falsehood perished: for Falsehood is (by its nature) bound to perish." 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 Muhammad SAW to mankind): "Each one does according to Shakilatihi (i.e. his way or his religion or his intentions, etc.), and your Lord knows best of him whose path (religion, etc.) is right." 84
