Establish prayer at the decline of the sun [from its meridian] until the darkness of the night and [also] the Qur'an of dawn. Indeed, the recitation of dawn is ever 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 send down, of the Koran, that which is a healing and a mercy to the believers; and the unbelievers it increases not, except in loss. 82 Whenever We bestow favours upon man, he arrogantly turns away and draws aside; and whenever evil visits him, he is in utter despair. 83 Say: Every one acts according to his manner; but your Lord best knows who is best guided in the path. 84
