Do not say of anything: 'I will do it tomorrow' 23 without [adding], "if God so wills." Remember your Lord whenever you might forget and say, "I trust my Lord will guide me to that which is even nearer to the right path than this." 24 [Some say], "They stayed in their cave three hundred years," and to that some have added another nine years. 25 You say: "God only knows how long they stayed. He alone knows the secrets of the heavens and the earth. How distinctly He sees and hears! They have no other guardian but Him, and He does not share His authority with any one." 26 And rehearse thou that which hath been revealed unto thee of the Book of thy Lord; and none may alter His Words, and never wilt thou find beside Him a covert. 27 And keep yourself patient [by being] with those who call upon their Lord in the morning and the evening, seeking His countenance. And let not your eyes pass beyond them, desiring adornments of the worldly life, and do not obey one whose heart We have made heedless of Our remembrance and who follows his desire and whose affair is ever [in] neglect. 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 As for those who believe and do good We shall not cause their reward to be lost. 30 These! for them are Gardens Everlasting whereunder rivers flow; bedecked they shall be therein with bracelets of gold, and wear they shall green robes of satin and brocade, reclining therein on the couches; excellent the reward, and goodly the resting-place! 31
