“ Yea, Woe to him; How he plotted!-20Then he looked round;21 Then he frowned and he scowled;22 Then he turned back and was haughty;23 Then said he: "This is nothing but magic, derived from of old;24 "This is nothing but the word of a mortal!"25 Soon will I cast him into Hell-Fire!26 And what will explain to thee what Hell-Fire is? 27 Naught doth it permit to endure, and naught doth it leave alone!-28 Darkening and changing the colour of man!29 Over it are Nineteen. 30 And We have set none but angels as Guardians of the Fire; and We have fixed their number only as a trial for Unbelievers,- in order that the People of the Book may arrive at certainty, and the Believers may increase in Faith,- and that no doubts may be left for the People of the Book and the Believers, and that those in whose hearts is a disease and the Unbelievers may say, "What symbol doth Allah intend by this?" Thus doth Allah leave to stray whom He pleaseth, and guide whom He pleaseth: and none can know the forces of thy Lord, except He and this is no other than a warning to mankind.” Muddaththir: 74: 20-31
