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 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 say, "My Lord, cause me to enter a sound entrance and to exit a sound exit and grant me from Yourself a supporting authority." 80 Say, "Truth has come and falsehood has disappeared. Falsehood is always bound to wither away." 81 And We reveal of the Qur'an that which is a healing and a mercy for believers though it increase the evil-doers in naught save ruin. 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, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." 84
