A highly dramatic scene: The father leans over the defenseless boy, the knife glinting in his hand - just then, an angel commands him at the last moment to sacrifice a ram instead of his own son. The biblical story of Abraham and Isaac is well-known. That it gave philosopher Kierkegaard a sleepless night at Berlin's Gendarmenmarkt, during which a divine mouse appeared to him to discuss questions of mercy - only Sibylle Lewitscharoff knows that. What the Quran makes of this narrative, how it refers to Isaac as a lesser figure while highlighting Abraham's firstborn, Ishmael, is told to us by Najem Wali. From Abraham to Eve, from Noah to Satan: Eight figures from the Bible and the Quran have been brought together by the linguistically powerful religious scholar Sibylle Lewitscharoff and the Iraqi-German author Najem Wali, a free spirit and moralist.
