His is all that is in the heavens and all that is in the earth. Have you any authority to support (that Allah has taken a son)? Do you ascribe to Allah something of which you have no knowledge? 68 Say: "Those who fabricate lies about God will never succeed." 69 A brief enjoyment in the world; then unto Us is their return; then We will make them taste a severe torment, in that they have been disbelieving. 70
