After Surur's death on 18 Rabi al-Thani 1202 AH (c. 27 January 1788), his brother Abd al-Mu'in assumed the Emirate.
News of Surur's death reached Istanbul in mid-Sha'ban (May 1788), and Sultan Abdul Hamid I confirmed Ghalib's appointment.
The imperial firman (proclamation) and khil'ah (robe of honor) arrived in Mecca on 29 Dhi al-Qi'dah 1202 AH (c. 1 September 1788).
On 24 Jumada al-Awwal (c. 20 February 1789), Ghalib and his brothers negotiated a peace agreement with the mediation of Sayyid Nasir ibn Mastur and several leading ulama.
[8] Muhammad Ali exiled Ghalib to Egypt, but in 1814 the central government arranged for him to be moved along with his family to Selanik (Thessaloniki).
