Establish worship at the going down of the sun until the dark of night, and (the recital of) the Qur'an at dawn. Lo! (the recital of) the Qur'an at dawn is ever witnessed. 78 And during a part of the night, pray Tahajjud beyond what is incumbent on you; maybe your Lord will raise you to a position of great glory. 79 Say: "O my Lord! Let my entry be by the Gate of Truth and Honour, and likewise my exit by the Gate of Truth and Honour; and grant me from Thy Presence an authority to aid (me)." 80 And say thou: the truth is come, and falsehood hath vanished; verily falsehood is ever vanishing. 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 bestow favor upon the disbeliever, he turns away and distances himself; and when evil touches him, he is ever despairing. 83 Say: "Everyone acts in a manner peculiar to himself - and your Sustainer is fully aware as to who has chosen the best path." 84
