And never say about anything: "I shall certainly do this tomorrow" 23 Except [when adding], "If Allah wills." And remember your Lord when you forget [it] and say, "Perhaps my Lord will guide me to what is nearer than this to right conduct." 24 [Some say], "They stayed in their cave three hundred years," and to that some have added another nine years. 25 Say: Allah is Best Aware how long they tarried. His is the Invisible of the heavens and the earth. How clear of sight is He and keen of hearing! They have no protecting friend beside Him, and He maketh none to share in His government. 26 And recite what has been revealed to you of the Book of your Lord, there is none who can alter His words; and you shall not find any refuge besides Him. 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 [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 Verily those who believe and work the righteous works - verily We waste not the hire of one who doth well in regard to his work. 30 There will be gardens of Eden for them, with rivers flowing by, where they will be decked in bracelets of gold, with silken robes of green and of brocades to wear, reclining on couches. How excellent the guerdon, and excellent the resting-place! 31
