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 And forego sleep* in some part of the night – an increase for you**; it is likely your Lord will set you on a place where everyone will praise you***. (* For worship. ** Obligatory only upon the Holy Prophet. *** On the Day of Resurrection.) 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 And when We bestow favor on man, he turns aside and behaves proudly, and when evil afflicts him, he is despairing. 83 Say, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." 84
