Descendants of Baha'u'llah gradually integrated themselves into Islamic society.

In 1948 a fierce political upheaval erupted in the Holy Land. The State of Israel was founded, bringing an end to the British Mandate. War broke out between Arabs and Jews and a great many Arabs fled the country. During this period Shoghi Effendi remained in Haifa and, in the face of great dangers and severe difficulties, carried on his work as usual, including the building of the superstructure of the Shrine of the Bab. But the rest of the family, who were Covenant-breakers, allied themselves with the Arab community and fled the land. Among them were the family of Mirza Jalal Shahid, which included Ruha Khanum, the daughter of 'Abdu'l-Bahá; Tuba Khanum, another daughter of 'Abdu'l-Bahá, and her son Ruhi, his wife Zahra and his brother; three cousins of Dr Farid; and Nayyir Afnan, his wife Ruhangiz (sister of Shoghi Effendi) and their children. Others who fled to Lebanon were Badi'u'llah (next in command to the Arch-breaker of the Covenant) and his relatives, together with those Bahá'ís who were disloyal to Shoghi Effendi. As time went on these people, who were already cut off from the Holy Family by virtue of their association with the enemies of the Faith, integrated themselves into Islamic society.
