Arab Caliph Umar Captures Jerusalem in 637 CE and Allows Jews to Settle in in Jerusalem
In 637 CE, Byzantine Bishop Sophronius surrendered Jerusalem to Caliph Umar, a companion of Mohammed. A fragment of a Jewish Chronicle found in the Cairo Genizah, written in Judaeo-Arabic, confirms that Caliph Umar wanted to grant permission to 200 Jewish families to settle in Jerusalem. The Christian Patriarch was dead set against it. It was finally agreed to settle 70 Jewish families in Jerusalem.
