Establish the prayer at the decline of the sun till the darkening of the night and the Koran recital at dawn. Surely, the Koran recital at dawn is 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 nullified." Verily falsehood is perishable. 81 And We send down from the Quran that which is a healing and a mercy to those who believe (in Islamic Monotheism and act on it), and it increases the Zalimun (polytheists and wrong-doers) nothing but loss. 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 works according to his manner, but your Lord is most knowing of who is best guided in way." 84
