[2][3][4][5] In 1171 AH (1758) Sayyid Abd Allah al-Fa'ar, a former ally, attempted to depose Musa'id with support from the Egyptian and Syrian Emirs of the Hajj, Keşkeş Hüseyin Bey and Çeteci Abdullah Pasha.
This time aided by an official firman, he deposed Musa'id and replaced him with his brother Ja'far ibn Sa'id in August 1759.
After the departure of Çeteci Abdullah and the Hajj caravan, Ja'far abdicated to his brother on 14 Muharram 1173 AH (c. 6 September 1759).
[6][7][8][9] Musa'id sent a complaint to Sultan Mustafa III against Çeteci Abdullah, to which he attached the testimonies of Mecca's four Muftis.
Having lost his ally, Abd Allah ibn Husayn mounted his own offensive against Musa'id, only to be defeated in Muharram 1184 AH, after which he returned to Egypt.
