Never say of something, "I shall do it tomorrow," 23 without [adding], "if God so wills." Remember your Lord whenever you might forget and say, "I trust my Lord will guide me to that which is even nearer to the right path than this." 24 [Some say], "They stayed in their cave three hundred years," and to that some have added another nine years. 25 (Muhammad), say, "God knows best how long they stayed there; to Him belongs the unseen of both the heavens and the earth. How clear is His sight and how keen His hearing! No one other than Him is their guardian and no one shares His Judgment. 26 Recite what is revealed to you in the Book of your Lord. No one can change His Words. You shall find no refuge other than Him. 27 And restrain yourself along with those who pray to their Lord morning and evening, seeking His pleasure; and may not your sight fall on anything besides them; would you desire the adornment of the life of this world? And do not follow him whose heart We have made neglectful of Our remembrance – the one who has followed his own desires and his matter has crossed the limits. 28 And say: "The truth is from your Lord." Then whosoever wills, let him believe, and whosoever wills, let him disbelieve. Verily, We have prepared for the Zalimun (polytheists and wrong-doers, etc.), a Fire whose walls will be surrounding them (disbelievers in the Oneness of Allah). And if they ask for help (relief, water, etc.) they will be granted water like boiling oil, that will scald their faces. Terrible the drink, and an evil Murtafaqa (dwelling, resting place, etc.)! 29 Verily those who believe and work the righteous works - verily We waste not the hire of one who doth well in regard to his work. 30 As for such, theirs will be Gardens of Eden, wherein rivers flow beneath them; therein they will be given armlets of gold and will wear green robes of finest silk and gold embroidery, reclining upon throne therein. Blest the reward, and fair the resting-place! 31
