In a time when hate crimes are common, the author of And Man Created God asks whether tolerance can be expected to heal today's breach between Islam and the post-Christian West. Surveying the intertwined histories of the monotheistic religions, Selina O'Grady draws new conclusions from the stories of Umar, the 7th century caliph who presided over the largest empire ever known; Magna Carta signer King John, who almost converted to Islam; and Ibn Abd al-Wahhab, creator of the religious-military alliance with the House of Saud that still survives today.
