Perform the prayer at the sinking of the sun to the darkening of the night and the recital of dawn; surely the recital of dawn is witnessed. 78 And of the night - keep the vigil therein, as an act of supererogation for thee; belike thy Lord will raise thee up in a station praised. 79 Say, "Lord, grant me an honourable entrance and an honourable exit, and sustain me with Your power." 80 And say: "Truth has (now) arrived, and Falsehood perished: for Falsehood is (by its nature) bound to perish." 81 And We reveal of the Quran that which is a healing and a mercy to the believers, and it adds only to the perdition of the unjust. 82 When We are gracious to man he turns away and moves aside; yet when evil befalls him he begins to despair. 83 Say, "Everyone does as he wants. Your Lord knows best who has the right guidance." 84
