On Friday, 1 Safar 1041 AH (29 August 1631), Abd Allah abdicated and appointed Muhammad and Zayd ibn Muhsin as his successors.
[2][3] Muhammad and Zayd reigned together until Sha'ban (March 1632), when Mecca was captured by a rebel Yemeni army led by the commanders Kor Mahmud and Ali Bey.
The rebels allied with Nami ibn Abd al-Muttalib, a rival cousin, and marched on Mecca after they were refused permission to enter the city on their way to Egypt.
Muhammad and Zayd, accompanied by Mustafa Bey, governor of Jeddah, fought the rebels and were defeated near Wadi al-Biyar on Wednesday, 25 Sha'ban (17 March 1632).
[4][3] After Zayd fled with the remaining ashraf to Wadi Marr al-Zahran, Nami entered Mecca with the rebels and took possession of the Emirate.
