Observe the service of prayer from the sun's declining from the meridian to the darkening of the night, and the recitation at dawn. Indeed the Recitation at dawn is palpably evident. 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: '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 been banished; it is doomed to banishment.'" 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 Yet when We bestow Our favours on man, he turns away and becomes remote on his side (instead of coming to Us), and when evil seizes 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
