And never say thou of a thing: verily I am going to do that on the morrow. 23 Without (adding), "if God may please;" and think of your Lord in ease you forget, and say: "Perhaps my Lord will show me a nearer way to rectitude." 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 And recite, [O Muhammad], what has been revealed to you of the Book of your Lord. There is no changer of His words, and never will you find in other than Him a refuge. 27 Keep yourself attached to those who call on their Lord, morning and evening, seeking His pleasure; and do not let your eyes turn away from them, desiring the attraction of worldly life; and do not obey one whose heart We have made heedless of Our remembrance, one who pursues his own whims and becomes dissolute. 28 And say: "The truth [has now come] from your Sustainer: let, then, him who wills, believe in it, and let him who wills, reject it." Verily, for all who sin against themselves [by rejecting Our truth] We have readied a fire whose billowing folds will encompass them from all sides; and if they beg for water, they will be given water [hot] like molten lead, which will scald their faces: how dreadful a drink, and how evil a place to rest! 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 As for such, theirs will be Gardens of Eden, wherein rivers flow beneath them; therein they will be given armlets of gold and will wear green robes of finest silk and gold embroidery, reclining upon throne therein. Blest the reward, and fair the resting-place! 31
