And never say of anything, "Indeed, I will do that 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 the Cave three hundred years and to that they added nine more. 25 Say, "Allah is most knowing of how long they remained. He has [knowledge of] the unseen [aspects] of the heavens and the earth. How Seeing is He and how Hearing! They have not besides Him any protector, and He shares not His legislation with anyone." 26 And recite what has been revealed to you of the Book of your Lord, there is none who can alter His words; and you shall not find any refuge besides Him. 27 And contain thyself in patience by the side of all who at morn and at evening invoke their Sustainer, seeking His countenance, and let not thine eyes pass beyond them in quest of the beauties of this world's life; and pay no heed to any whose heart We have rendered heedless of all remembrance of Us because he had always followed [only] his own desires, abandoning all that is good and true. 28 And say thou: the truth is from your Lord; let him therefore who will, believe, and let him who will, disbelieve. Verily We have gotten ready for the wrong-doers a Fire the awnings whereof shall encompass them; and if they cry for relief they shall be relieved with water like the dregs of oil scalding their faces. Ill the drink, and vile 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 those -- theirs shall be Gardens of Eden, underneath which rivers flow; therein they shall be adorned with bracelets of gold, and they shall be robed in green garments of silk and brocade, therein reclining upon couches -- O, how excellent a reward! And O, how fair a resting-place! 31
