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 [Some say], "They stayed in their cave three hundred years," and to that some have added another nine years. 25 Say, “Allah well knows how long they stayed; for Him only are the hidden of the heavens and the earth; how well He sees and hears! They do not have any supporter besides Him; and He does not associate anyone in His command.” 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 And say, "The truth is from your Lord, so whoever wills - let him believe; and whoever wills - let him disbelieve." Indeed, We have prepared for the wrongdoers a fire whose walls will surround them. And if they call for relief, they will be relieved with water like murky oil, which scalds [their] faces. Wretched is the drink, and evil is the 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 For them are everlasting Gardens of Eden, beneath which rivers flow – in it they will be given bracelets of gold to adorn, and shall wear green clothes made of fine silk and gold embroidery, reclining upon thrones in it; what an excellent reward; and what an excellent abode is Paradise! 31
