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 And say: My Lord! make me to enter a goodly entering, and cause me to go forth a goodly going forth, and grant me from near Thee power to assist (me). 80 And say: "Truth has come and falsehood nullified." Verily falsehood is perishable. 81 We send down (stage by stage) in the Qur'an that which is a healing and a mercy to those who believe: to the unjust it causes nothing but loss after 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 one acts according to his disposition, but your Lord knows well who follow the right path." 84
