BE CONSTANT in [thy] prayer from the time when the sun has passed its zenith till the darkness of night, and [be ever mindful of its] recitation at dawn: for, behold, the recitation [of prayer] at dawn is indeed witnessed [by all that is holy]. 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 say: My Lord! Cause me to come in with a firm incoming and to go out with a firm outgoing. And give me from Thy presence a sustaining Power. 80 Say: 'Truth has come and falsehood has vanished. Indeed, falsehood will certainly vanish' 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 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: "Everyone acts according to his own disposition: But your Lord knows best who it is that is best guided on the Way." 84
