Say your prayers from the decline of the sun, until nightfall; and at dawn -- the recitation at dawn is indeed witnessed. 78 As for the night there is a voluntary deed for you to keep vigil in part it. Perhaps your Lord will raise you to a praiseworthy station. 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 disappeared. Falsehood is always bound to wither away." 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, "Everyone does as he wants. Your Lord knows best who has the right guidance." 84
