Chronicle, a fragment of which is preserved in the Cairo Geniza, also confirms that it was ‘Umar who gave permission to the Jews to settle in Jerusalem and on the basis of his decision seventy Jewish families came from Tiberias and settled there.
This was preceded by bargaining between the Jews and the patriarch, in the presence of the caliph; the Jews requested residence permits for Jerusalem for two hundred families while the patriarch was only ready to agree to fifty, until ‘Umar decided on the number he thought fitting.
