The descendants of the Prophet ﷺ did not remain in one place. From their origin in the Hijaz — in Makkah and Madinah — they dispersed, over the early Islamic centuries, across the entire Muslim world, carried outward by the upheavals of their times and by a mission to spread Islam and sacred knowledge. This dispersal was not a single migration but a series of great streams, flowing in different directions, to different lands, founding different communities — yet all carrying the same prophetic blood. To understand the Sayyids today is to understand these journeys.
Why They Left the Hijaz
The descendants of the Prophet ﷺ often lived under suspicion and persecution in the early centuries, particularly under caliphates that feared their prestige and the loyalty they commanded. The Battle of Fakhkh near Makkah in 169 AH, in which many of the descendants of Sayyiduna Ali رضي الله عنه left this world by the Abbasids, scattered survivors across the Muslim world. Later, the Mongol devastation of the eastern Islamic lands in the seventh century AH uprooted scholarly families from Central Asia and sent them migrating in search of safety. Political instability in Hadramawt drove the Sayyids of Yemen outward across the Indian Ocean. In every case, hardship became the means by which the prophetic lineage — and the Islam it carried — reached new lands.
West: The Idrisids and the Sharifs of the Maghreb
One of the earliest and most consequential streams flowed west. Idris ibn Abdillah — a great-grandson of Sayyiduna al-Hasan ibn Ali رضي الله عنه and a survivor of the Battle of Fakhkh — fled across North Africa and arrived in the Maghreb around 172 AH. Welcomed by the Berber tribes, he founded the Idrisid dynasty, the first Islamic state in Morocco, and his son Idris II established Fez as its capital — a city that would become one of the great centres of Islamic learning, home to al-Qarawiyyin, regarded as among the oldest universities in the world. The Idrisids established the principle of Sharifian rule — legitimacy through descent from the Prophet ﷺ — that has shaped Morocco to this day. From them and from later Hasani migrations descend the great Sharifian families of Morocco, the later Sadi and Alawi dynasties, and many of the Ashraf of Mauritania, the Sahara, and West Africa, who carried Islam and scholarship deep into the African continent.
East: The Sayyids of Central Asia
Another great stream flowed east, into Khurasan and Transoxiana — the lands of Central Asia. Descendants of the Prophet ﷺ settled in the great cities of Islamic learning: Bukhara, Samarqand, Termez, Balkh, and Gardez. There they became eminent scholarly and spiritual families, contributing to the extraordinary flowering of Islamic scholarship that these cities produced. The Sayyids of Bukhara, the Tirmidhi Sayyids of Termez, the Gardezi Sayyids — these families combined prophetic lineage with deep learning, and many of them would later migrate again, carrying both their blood and their knowledge into the Indian subcontinent, as the next article explores in detail.
South: The Ba Alawi and the Indian Ocean
A third great stream flowed south, into Yemen and then across the Indian Ocean. Imam Ahmad ibn Isa al-Muhajir — “the Migrant” — a descendant of Sayyiduna al-Husayn رضي الله عنه through Imam Jafar al-Sadiq رحمه الله, left Basra in 317 AH and settled in the Hadramawt valley of Yemen. His descendants became the Ba Alawi Sadat, a community of scholar-saints who, over the following centuries, carried Sunni Islam of the Shafii school across the entire Indian Ocean rim — to the Malabar coast of India, to East Africa (Zanzibar, Lamu, the Comoros), and to the Malay Archipelago (Indonesia, Malaysia, and the southern Philippines). They spread Islam not by conquest but by character, scholarship, trade, and marriage — one of the most effective and peaceful missionary movements in the history of religion.

Why did the descendants of the Prophet ﷺ leave the Hijaz?
Largely because of persecution and political instability. The Battle of Fakhkh (169 AH) scattered survivors across the Muslim world; the Mongol devastation of Central Asia uprooted scholarly families; and instability in Hadramawt drove the Yemeni Sayyids across the Indian Ocean. In each case, hardship became the means by which the prophetic lineage and the Islam it carried reached new lands.
Who were the Idrisids?
The Idrisids were the first Islamic dynasty of Morocco, founded by Idris ibn Abdillah — a great-grandson of Sayyiduna al-Hasan رضي الله عنه who fled west after the Battle of Fakhkh. They founded Fez and its great centre of learning, al-Qarawiyyin, and established the principle of Sharifian rule that shaped Morocco to this day. From them descend many of the Sharifian families of the Maghreb and West Africa.
How did the Ba Alawi Sayyids spread Islam?
The Ba Alawi, descendants of Sayyiduna al-Husayn رضي الله عنه who settled in Hadramawt, carried Sunni Shafii Islam across the Indian Ocean — to India’s Malabar coast, East Africa, and the Malay Archipelago. They spread Islam not by conquest but through character, scholarship, trade, and marriage, in one of the most peaceful and effective missionary movements in religious history.
