Establish prayer at the decline of the sun [from its meridian] until the darkness of the night and [also] the Qur'an of dawn. Indeed, the recitation of dawn is ever witnessed. 78 And rise from thy sleep and pray during part of the night [as well,] as a free offering from thee, and thy Sustainer may well raise thee to a glorious station [in the life to come]. 79 And say thou: O my Lord! cause me to enter a rightful entrance and cause me to go forth with a rightful outgoing, and appoint for me from before Thee an authority helpful. 80 And say: "The truth has now come [to light,] and falsehood has withered away: for, behold, all falsehood is bound to wither away!" 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 And when We make life pleasant unto man, he turneth away and is averse; and when ill toucheth him he is in despair. 83 Say: Every one acts according to his manner; but your Lord best knows who is best guided in the path. 84
