Nor say of anything, "I shall be sure to do so and so 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 AND [some people assert,] "They remained in their cave three hundred years"; and some have added nine [to that number]. 25 Say: "Allah knows best how long they stayed. With Him is (the knowledge of) the unseen of the heavens and the earth. How clearly He sees, and hears (everything)! They have no Wali (Helper, Disposer of affairs, Protector, etc.) other than Him, and He makes none to share in His Decision and His Rule." 26 (O Prophet), recite to them from the Book of your Lord what has been revealed to you for none may change His words; (and were you to make any change in His words) you will find no refuge from 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: (It is) the truth from the Lord of you (all). Then whosoever will, let him believe, and whosoever will, let him disbelieve. Lo! We have prepared for disbelievers Fire. Its tent encloseth them. If they ask for showers, they will be showered with water like to molten lead which burneth the faces. Calamitous the drink and ill the resting-place! 29 Lo! as for those who believe and do good works - Lo! We suffer not the reward of one whose work is goodly to be lost. 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
