And never say of anything, "I shall do such and such thing tomorrow." 23 but only, 'If God will'; and mention thy Lord, when thou forgettest, and say, 'It may be that my Lord will guide me unto something nearer to rectitude than this.' 24 And they stayed in their Cave for three hundred years* and nine more*. (* 300 according to the Solar calendar and 309 according to the Lunar calendar.) 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 that which hath been revealed unto thee of the Scripture of thy Lord. There is none who can change His words, and thou wilt find no refuge beside Him. 27 And restrain thyself with those who call upon their Lord at morning and evening, desiring His countenance, and let not thine eyes turn away from them, desiring the adornment of the present life; and obey not him whose heart We have made neglectful of Our remembrance so that he follows his own lust, and his affair has become all excess. 28 Say," Truth comes from your Lord. Let people have faith or disbelieve as they chose." For the unjust We have prepared a fire which will engulf them with its (flames). Whenever they cry for help they will be answered with water as hot as molted brass which will scald their faces. How terrible is such a drink and such a resting place! 29 Surely those who believe, and do deeds of righteousness -- surely We leave not to waste the wage of him who does good works; 30 They shall dwell in the Gardens of Eternity, beneath which streams flow. There they will be adorned with bracelets of gold, will be arrayed in green garments of silk and rich brocade, and will recline on raised couches. How excellent is their reward, and how nice their resting-place!" 31
