And never say about anything that, “I will do this tomorrow.” 23 Except “If Allah wills”; and remember your Lord when you forget, and say, “It is likely that my Lord will guide me to a more accurate way of virtue than this.” 24 And (it is said) they tarried in their Cave three hundred years and add nine. 25 Say: "God knows best how long they remained [there]. His [alone] is the knowledge of the hidden reality of the heavens and the earth: how well does He see and hear! No guardian have they apart from Him, since He allots to no one a share in His rule!" 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 contain thyself in patience by the side of all who at morn and at evening invoke their Sustainer, seeking His countenance, and let not thine eyes pass beyond them in quest of the beauties of this world's life; and pay no heed to any whose heart We have rendered heedless of all remembrance of Us because he had always followed [only] his own desires, abandoning all that is good and true. 28 Say, "This is the truth from your Lord. Let him who will, believe in it, and him who will, deny it." For the wrongdoers We have prepared a Fire which will cover them like a canopy, and if they beg for water, they will be given water as hot as molten lead, which will scald their faces: how dreadful a drink, and how evil a 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 Those will have gardens of perpetual residence; beneath them rivers will flow. They will be adorned therein with bracelets of gold and will wear green garments of fine silk and brocade, reclining therein on adorned couches. Excellent is the reward, and good is the resting place. 31
