And never say about anything: "I shall certainly do this tomorrow" 23 Except (with the saying), "If Allah will!" And remember your Lord when you forget and say: "It may be that my Lord guides me unto a nearer way of truth 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 (Muhammad), say, "God knows best how long they stayed there; to Him belongs the unseen of both the heavens and the earth. How clear is His sight and how keen His hearing! No one other than Him is their guardian and no one shares His Judgment. 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 And restrain yourself along with those who pray to their Lord morning and evening, seeking His pleasure; and may not your sight fall on anything besides them; would you desire the adornment of the life of this world? And do not follow him whose heart We have made neglectful of Our remembrance – the one who has followed his own desires and his matter has crossed the limits. 28 And proclaim, “The Truth is from your Lord”; so whoever wills may accept faith, and whoever wills may disbelieve – We have indeed prepared for the disbelievers a fire the walls of which will surround them; if they plead for water, their plea will be answered with water like molten metal which shall scald their faces; what an evil drink it is; and what an evil destination is hell! 29 Surely (as for) those who believe and do good, We do not waste the reward of him who does a good work. 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
