Sadaf is an ancient tribe and is deep-rood in history.

Its origins date back to the country of Yemen in the south of the Arabian Peninsula.

Sadafians migrated from Hadramout with the wave of migrations that followed the collapse of the famous Marib Dam.

After the advent of Islam Sadaf tribe was one of the first tribes that came to the Prophet in the ninth year of migration which was known as the year of Delegations, in Islam, and they were model Muslims.

The clan played a significant role in the movement of the Islamic conquests and it has strongly and effectively participated in the conquest of Egypt, especially in the siege of Fortress of Babylon, and in the conquest of Fayoum and Alexandria.

Then they settled in Fustat and they made a well-known plan, and they led a peaceful life there, so they inhabited it and made it their residence.
