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 And say: My Lord! Cause me to come in with a firm incoming and to go out with a firm outgoing. And give me from Thy presence a sustaining Power. 80 And say: "Truth has come and falsehood nullified." Verily falsehood is perishable. 81 And We reveal by means of the Qur'an that which is a healing and a mercy unto the believers, and it only increaseth the wrong-doers in loss. 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 one doth according to his rule of conduct, and thy Lord is Best Aware of him whose way is right. 84
