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 Say a supererogatory prayer at the hour of the first watch: Your Lord may raise you to a most exalted station. 79 And pray: "O my Lord, let my entry be with honour, and let my exit be with honour, and grant me power from You which would help (sustain) me." 80 And say: The truth has come and the falsehood has vanished; surely falsehood is a vanishing (thing). 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: 'Every man works according to his own manner; but your Lord knows very well what man is best guided as to the way.' 84
