The Quaran says: “Allah forbid that He Himself should beget a son!” (Sura 19:35-36); “Say: ‘Praise be to Allah who has never begotten a son, who has no partner in His kingdom” (Sura 17:111). The Bible says, “For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.”
