Say your prayer when the sun declines until the darkness of night and also at dawn. Dawn is certainly witnessed (by the angels of the night and day). 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 pray: "O my Lord, let my entry be with honour, and let my exit be with honour, and grant me power from You which would help (sustain) me." 80 And say: "Truth has come and falsehood nullified." Verily falsehood is perishable. 81 And We send down in the Qur’an that which is a cure for the Muslims, and a mercy – and it increases only ruin for the unjust. 82 And when We bestow Our Grace on man (the disbeliever), he turns away and becomes arrogant, far away from the Right Path. And when evil touches him he is in great 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
