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 as for the night, keep vigil a part of it, as a work of supererogation for thee; it may be that thy Lord will raise thee up to a laudable station. 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: 'The truth has come, and falsehood has vanished away; surely falsehood is ever certain to vanish.' 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 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 (O Muhammad SAW to mankind): "Each one does according to Shakilatihi (i.e. his way or his religion or his intentions, etc.), and your Lord knows best of him whose path (religion, etc.) is right." 84
