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 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, "Truth has come, and falsehood has departed. Indeed is falsehood, [by nature], ever bound to depart." 81 THUS, step by step, We bestow from on high through this Qur'an all that gives health [to the spirit] and is a grace unto those who believe [in Us,] the while it only adds to the ruin of evildoers: 82 for [it often happens that] when We bestow Our blessings upon man, he turns away and arrogantly keeps aloof [from any thought of Us]; and when evil fortune touches him, he abandons all hope. 83 Say: 'Each human works in his own manner. But your Lord knows very well who is best guided on the way' 84
