Establish worship at the going down of the sun until the dark of night, and (the recital of) the Qur'an at dawn. Lo! (the recital of) the Qur'an at dawn is ever 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 Say, 'Truth has come and falsehood has been banished; it is doomed to banishment.'" 81 And We reveal of the Qur'an that which is a healing and a mercy for believers though it increase the evil-doers in naught save ruin. 82 When We are gracious to man he turns away and moves aside; yet when evil befalls him he begins to despair. 83 Say: 'Each human works in his own manner. But your Lord knows very well who is best guided on the way' 84
