Do not say of anything: 'I will do it 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 remained in their cave three hundred years and (some) add (another) nine. 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 (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 Restrain thyself along with those who cry unto their Lord at morn and evening, seeking His Countenance; and let not thine eyes overlook them, desiring the pomp of the life of the world; and obey not him whose heart We have made heedless of Our remembrance, who followeth his own lust and whose case hath been abandoned. 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 [But,] behold, as for those who attain to faith and do righteous deeds - verily, We do not fail to requite any who persevere in doing good: 30 These! For them will be 'Adn (Eden) Paradise (everlasting Gardens); wherein rivers flow underneath them, therein they will be adorned with bracelets of gold, and they will wear green garments of fine and thick silk. They will recline therein on raised thrones. How good is the reward, and what an excellent Murtafaqa (dwelling, resting place, etc.)! 31
