Never say of something, "I shall do it tomorrow," 23 without [adding,] "if God so wills." And if thou shouldst forget [thyself at the time, and become aware of it later,] call thy Sustainer to mind and say: "I pray that my Sustainer guide me, even closer than this, to a consciousness of what is right!" 24 And they stayed in their Cave three hundred (solar) years, and add nine (for lunar years). 25 Say, "God knows best how long they stayed in it." Only God has knowledge of the unseen in the heavens and on the earth. How well He sees and how well He hears! Man has no other guardian besides Him. He allows none to share His sovereignty. 26 And recite (and teach) what has been revealed to thee of the Book of thy Lord: none can change His Words, and none wilt thou find as a refuge other than Him. 27 And keep yourself (O Muhammad SAW) patiently with those who call on their Lord (i.e. your companions who remember their Lord with glorification, praising in prayers, etc., and other righteous deeds, etc.) morning and afternoon, seeking His Face, and let not your eyes overlook them, desiring the pomp and glitter of the life of the world; and obey not him whose heart We have made heedless of Our Remembrance, one who follows his own lusts and whose affair (deeds) has been lost. 28 Say, "The truth is from your Lord": Let him who will believe, and let him who will, reject (it): for the wrong-doers We have prepared a Fire whose (smoke and flames), like the walls and roof of a tent, will hem them in: if they implore relief they will be granted water like melted brass, that will scald their faces, how dreadful the drink! How uncomfortable a couch to recline on! 29 Indeed, those who have believed and done righteous deeds - indeed, We will not allow to be lost the reward of any who did well in deeds. 30 They will be admitted to the gardens of Eden wherein streams flow. They will rest on soft couches, decked with bracelets of gold and clothed in green silk garments and shining brocade. How blissful is such a reward and resting place! 31
