“What about Islamic law? On this topic, it is useful to turn to Robert Jackson, a giant figure in American law and politics—FDR’s attorney general, justice of the Supreme Court, and chief prosecutor of the war crimes trials at Nuremberg. In 1955, Justice Jackson penned the foreword to a book called Law in the Middle East. Unlike today’s government officials, Justice Jackson thought sharia was a subject worthy of close study. And here is what he concluded:”
“In any broad sense, Islamic law offers the American lawyer a study in dramatic contrasts. Even casual acquaintance and superficial knowledge—all that most of us at bench or bar will be able to acquire—reveal that its striking features relative to our law are not likenesses but inconsistencies, not similarities but contrarieties. In its source, its scope and its sanctions, the law of the Middle East is the antithesis of Western law.”
