And do not say of anything: Surely I will 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 tarried in the Cave three hundred years, and to that they added nine more. 25 Say: "God knows best how long they remained [there]. His [alone] is the knowledge of the hidden reality of the heavens and the earth: how well does He see and hear! No guardian have they apart from Him, since He allots to no one a share in His rule!" 26 And rehearse thou that which hath been revealed unto thee of the Book of thy Lord; and none may alter His Words, and never wilt thou find beside Him a covert. 27 Persevere with those who call on their Lord morning and evening, seeking His magnificence. Do not turn your eyes away from them, seeking the splendours of this world, and do not follow him whose heart We have made oblivious to Our remembrance, who follows his own lust and exceeds the bound. 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 The righteously striving believers should know that We do not neglect the reward of those who do good deeds. 30 These it is for whom are gardens of perpetuity beneath which rivers flow, ornaments shall be given to them therein of bracelets of gold, and they shall wear green robes of fine silk and thick silk brocade interwoven with gold, reclining therein on raised couches; excellent the recompense and goodly the resting place. 31
