Establish thou the prayer from the declination of the sun to the darkening of the night, and the recitation at the dawn; verily the recitation at the dawn is ever borne witness to. 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 come and falsehood nullified." Verily falsehood is perishable. 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 Yet when We bestow favors upon mankind he turns his back and withdraws to one side. But when evil befalls him, he despairs. 83 Say, "Everyone does as he wants. Your Lord knows best who has the right guidance." 84
