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 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 pray: "My Lord! Cause me to enter wherever it be, with Truth, and cause me to exit, wherever it be, with Truth, and support me with authority from Yourself." 80 And say: "Truth has come and falsehood nullified." Verily falsehood is perishable. 81 What We have sent down of the Qur'an is a healing and a grace for the faithful, and adds only loss for the sinners. 82 When We bestow a favour upon a person, he turns his back and draws aside; and when evil afflicts him he gives himself up to despair. 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
