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 as for the night, keep vigil a part of it, as a work of supererogation for thee; it may be that thy Lord will raise thee up to a laudable station. 79 And say: 'My Lord, lead me in with a just ingoing, and lead me out with a just outgoing; grant me authority from Thee, to help me.' 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 And We send down, of the Koran, that which is a healing and a mercy to the believers; and the unbelievers it increases not, except in loss. 82 And when We bestow favours upon man, he turns away and goes far away towards himself; and when evil touches him he despairs. 83 Say thou: everyone worketh after his disposition, and your Lord is the Best Knower of him who is best guided on the way. 84
