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 tarried in their cave three hundred years and added nine. 25 Say, "God knows best how long they stayed in it." Only God has knowledge of the unseen in the heavens and on the earth. How well He sees and how well He hears! Man has no other guardian besides Him. He allows none to share His sovereignty. 26 Read whatever is revealed to you from the Book of your Lord. No one can change His words and you can never find any refuge other than Him. 27 Restrain thyself along with those who cry unto their Lord at morn and evening, seeking His Countenance; and let not thine eyes overlook them, desiring the pomp of the life of the world; and obey not him whose heart We have made heedless of Our remembrance, who followeth his own lust and whose case hath been abandoned. 28 Say," Truth comes from your Lord. Let people have faith or disbelieve as they chose." For the unjust We have prepared a fire which will engulf them with its (flames). Whenever they cry for help they will be answered with water as hot as molted brass which will scald their faces. How terrible is such a drink and such a resting place! 29 Surely (as for) those who believe and do good, We do not waste the reward of him who does a good work. 30 Those, they shall live in the Gardens of Eden, underneath which rivers flow. They shall be adorned with bracelets of gold and arrayed in green garments of silk, and brocade, reclining therein on couches; how excellent is their reward and how fine is their resting place! 31
