Most notably, the great majority of Somali clans claim to be descended from Aqil ibn Abi Talib, though this is historically untenable.
[1] Having initially fought against Muhammad at the Battle of Badr (624), in which he was taken prisoner and later bought free by his uncle Abbas ibn Abd al-Muttalib, he converted to Islam around 629 or 630.
[1] After the victory of the Muslims and the death of Muhammad in 632, Aqil lived in the military encampments of Kufa and Basra for a while, supporting his brother Ali (who ruled from Medina as the fourth caliph, 656 – 661).
The second caliph Umar (r. 634–644) appointed him to record the names of the members of the Quraysh in the clan register (the dīwān), and to arbitrate disputes with regard to genealogy.
Contrary to their father, a number of his sons decided to fight for the Hashimite cause and were martyred along with their cousin Husayn ibn Ali at the Battle of Karbala in 680.
'the House of Aqil'), appears to have contained a graveyard where a number of notable early Muslims (especially members of the Hashimite family, such as Muhammad's daughter and Ali's wife Fatima) are said to have been buried.
Finally, southern clans who practice agriculture such as the Rahanweyn trace their ancestry to Aqil through their common purported forefather Sab.
