Establish regular prayers - at the sun's decline till the darkness of the night, and the morning prayer and reading: for the prayer and reading in the morning carry their testimony. 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 Say: 'Lord, grant me an entrance of sincerity and an exit of sincerity, and give me from Yours a victorious 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 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: "Each one acts according to his disposition, but your Lord knows well who follow the right path." 84
