never say of 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 Say: 'God knows very well how long they tarried. To Him belongs the Unseen in the heavens and in the earth. How well He sees! How well He hears! They have no protector, apart from Him, and He associates in His government no one.' 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 And withhold yourself with those who call on their Lord morning and evening desiring His goodwill, and let not your eyes pass from them, desiring the beauties of this world's life; and do not follow him whose heart We have made unmindful to Our remembrance, and he follows his low desires and his case is one in which due bounds are exceeded. 28 Say: "The truth is from your Lord: So believe if you like, or do not believe if you will." We have prepared for the sinners a fire which will envelope them in its tent. If they ask for water they will be helped to liquid like molten brass that would scald their mouths. How evil the drink, and evil the resting-place! 29 Lo! as for those who believe and do good works - Lo! We suffer not the reward of one whose work is goodly to be lost. 30 they shall dwell in the Gardens of eternity where rivers flow at their feet. Reclining upon raised couches, they will be adorned with bracelets of gold, and will wear green robes of fine silk and heavy brocade. An excellent reward and an excellent resting place! 31
