Daud ibn Sulaiman
Daud ibn Sulaiman was a sultan of Kilwa from the Yemeni Mahdali dynasty, a son of Sultan Sulaiman ibn al-Hasan and brother of al-Hasan ibn Sulaiman, called Abu al-Mawahib, the father of gifts.
When their father died around 1308 while al-Hasan was away on pilgrimage to Mecca, Daud was placed on the Kilwa throne. He ruled for two years, then voluntarily stood down when his brother returned.
Al-Hasan's reign made Kilwa rich: he minted gold coins, began building the palace of Husuni Kubwa and earned the traveller Ibn Battuta's praise for his generosity. When al-Hasan died in 1333, Daud became sultan a second time.
