Later, when the edict was finally repealed in 1044 during the reign of Caliph Al-Mustansir of Cairo, only 27 percent of the Jewish converts to Islam returned to Judaism openly, although they too would remain Musta’arabi (culturally and linguistically Arab). The remainder continued to live as Muslim crypto-Jews in order to continue enjoying the economic advantages of Muslims, such as exemption from paying jizya and kharaj, the ability to sell their agricultural products to the foreign authorities, or gain employment in the government machinery. Many younger persons of Hebrew-origin (Jewish, Christian or Samaritan) saw it simultaneously possible to lead dual lives, incorporating their prior faith while being outwardly Muslim, and accruing material benefits.[11] Later, with the advent of Mamluk rule, Judaism had reached a breaking point in Palestine.[2]
