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: "O my Lord! Let my entry be by the Gate of Truth and Honour, and likewise my exit by the Gate of Truth and Honour; and grant me from Thy Presence an authority to aid (me)." 80 And say: "Truth has (now) arrived, and Falsehood perished: for Falsehood is (by its nature) bound to perish." 81 We send down in the Quran that which is healing and a mercy to those who believe; as for the evil-doers, it only increases their loss. 82 Whenever We bestow favours upon man, he arrogantly turns away and draws aside; and whenever evil visits him, he is in utter despair. 83 Say, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." 84
