Establish Prayer from the declining of the sun to the darkness of the night; and hold fast to the recitation of the Qur'an at dawn, for the recitation of the Qur'an at dawn is witnessed. 78 Say your special (tahajjud) prayer during some part of the night as an additional (obligatory) prayer for you alone so that perhaps your Lord will raise you to a highly praiseworthy position. 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 We sent down of the Koran that which is a healing and a mercy to believers, but to the harmdoers it does not increase them, except in loss. 82 When We do favors to the human being, he disregards it and turns away from it. When evil afflicts him, he becomes despairing. 83 Say, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." 84
