Ba 'Alawi sada
The Ba 'Alawi sada (Arabic: سادة باعلوي, romanized: sādat bā 'alawiy, lit. 'the descendants of ‘Alawi'), or the House of Ba 'Alawi (Arabic: آل باعلوي, romanized: Āl Bā 'alawiy), is a group of Hadhrami Sayyid families and social group originating in Hadhramaut in the southwest corner of the Arabian Peninsula. They trace their lineage to Ahmad al-Muhajir, himself a descendant of Muhammad, who emigrated from Basra to Hadhramaut in 931 (318H).
