He represents one of the early ancestors of the Bâ Alawi lineage in Yemen; he was the son of Ahmad ibn Isa al-Muhajir, who migrated from Basra to Hadramaut. Following his father he settled in the village of al-Sumal near Tarim, where he died in 383 AH (993 CE). His son Alawi was the first member of the family born in Yemen, and the entire Bâ Alawi (Al Ba Alawi) sada lineage descends through this branch. No cross-verified numeric coordinate exists for al-Sumal, so no map pin is placed.
