Perform the prayer at the sinking of the sun to the darkening of the night and the recital of dawn; surely the recital of dawn is 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 And pray: "My Lord! Cause me to enter wherever it be, with Truth, and cause me to exit, wherever it be, with Truth, and support me with authority from Yourself." 80 And say: "Truth has (now) arrived, and Falsehood perished: for Falsehood is (by its nature) bound to perish." 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, (O Prophet): "Each one acts according to his own manner. Your Lord knows well who is best-guided to the Right Path." 84
