With his first wife,
Sayyida Rabia, Muhammad al-Shaykh had three sons, but the two oldest had died while he was still alive (in 1550 and in 1551). Abdallah, the third, was 40 years old when he became sultan and received the name al-Ghalib Billah. Before that he had been vice-king of
Marrakesh and governor of
Fez. Shortly after Abdallah came to power, three of his younger brothers fled the country and joined the
Ottoman Turks.
Abd al-Malik and
Ahmad, both future Saadi sultans, spent 17 years in exile in the
Ottoman Empire, moving between
Algiers and
Constantinople, where they were trained by the Ottomans. ==Battle of Wadi al-Laban==
