Libya
The Sayyids in Libya are Sunni, including the former royal family, which is originally Zaidi-Moroccan (also known as the Senussi family). The El-Barassa Family are Ashraf as claimed by the sons of Abdulsalam ben Meshish, a descendant of Hassan bin Ali bin Abi Talib. South Asia
Although people in South Asia claim Hashemite descent, genealogy family trees are studied to authenticate claims. In 1901 the total number of Sayyids in British India was counted as 1,339,734. History of South Asian Sayyids
Sayyids migrated many centuries ago from different parts of the Middle East and Central Asia (Turkestan) during the invasion of the Mongols, Ghaznavid dynasty, Delhi Sultanate, and Mughal Empire, encompassing a timespan of roughly until the late 19th century. Sayyids migrated to Sindh, Uch, Bihar Sharif, Sheikhpura ,  and Attock Khurd (Punjab) and settled there very early. Other early migrant Sayyids moved deep into the south to the Deccan sultanates located in the Deccan Plateau region in the time of the Bahmani Sultanate, and later Golkonda, Nizam Shahi of Ahmednagar, Bijapur, Bidar, and Berar.
He migrated to Harar first, then settled in the southern part of Omnan which is now a part of Silte. Middle East
Men belonging to the Sayyid families or tribes in the Arab world used to wear white or ivory coloured daggers like jambiyas, khanjars or shibriyas to demarcate their nobility amongst other Arab men, although this custom has been restricted due to the local laws of the variously divided Arab countries.

Iran
Sayyids (in Persian: سید Seyyed) are found in vast numbers in Iran. The Chief of "National Organization for Civil Registration" of Iran declared that more than 6 million of Iranians are Sayyid. The majority of Sayyids migrated to Iran from Arab lands predominantly in the 15th to 17th centuries during the Safavid era. The Safavids transformed the religious landscape of Iran by imposing Twelver Shiism on the populace.
