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 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 And say, "Truth has come, and falsehood has departed. Indeed is falsehood, [by nature], ever bound to depart." 81 And We reveal of the Quran that which is a healing and a mercy to the believers, and it adds only to the perdition of the unjust. 82 Yet when We bestow favors upon mankind he turns his back and withdraws to one side. But when evil befalls him, he despairs. 83 Say, "Everyone does as he wants. Your Lord knows best who has the right guidance." 84
