Syed Ahmad Jajneri migrated to India from Baghdad during the reign of Muhammad of Ghor and later migrated to Bihar. He was the direct descendant of Zayd ibn Ali who was the grandson of Husayn ibn Ali and therefore his descendants are called Husseini(Zaidi)Sadaat. His descendants are mostly settled in Bihar Sharif, Munger, Sheikhpura and Jamui region of Bihar. Most prominent personalities of Sadaat of Bihar were from Desna, Bihar. For Example Syed Mohammed Saeed Raza, Abdul Qavi Desnavi and Sulaiman Nadvi. Desnas library, established in 1892, had thousands of old Persian and Urdu manuscripts. After the partition of India, during uncertain times of mass emigration to Pakistan, the books were donated to Khuda Bakhsh Khan Library in Patna, where a Desna section was established to house these treasures. Other famous personalities of Bihari Syed were Syed Sultan Ahmed, Syed Hasan Imam and Sir Imam Ali .

Genetic Y-DNA research
According to Islamic prophetic tradition, Muhammad was descended from Abraham through Ismail. Some researchers have suggested using Y chromosome genetic data from Sayyid groups and from Jewish and Samaritan sources to reconstruct genetic information about the historical Abraham. Tesayyud
In the Ottoman Empire, tax breaks for "the People of the House" encouraged many people to buy certificates of descent or forge genealogies; the phenomenon of teseyyüd – falsely claiming noble ancestry – spread across ethnic, class, and religious boundaries. In the 17th century, an Ottoman bureaucrat estimated that there were 300,000 impostors. In 18th-century Anatolia, nearly all upper-class urban people claimed descent from Muhammad. Prince Sayyid
