The mufti issued a fatwa to depose Sultan Selim on the twenty-first of Rabi' al-Awwal in the year 1282 AH, which corresponds to 1867 AD, stating, "He who enters Muslim lands is not fit to rule. God knows best." The army rejoiced at this and proclaimed the accession of Sultan Mustafa Khan IV. They then arrested him and confined him to one of the palaces, where he remained for approximately twenty years.

During his reign, Markos, the Patriarch of the Copts, passed away after serving for about twenty-four years, a period filled with hardships. The burdens of the military command and the confiscation of people's property, as previously explained, greatly troubled him. After him, Yusuf, the 107th patriarch, was appointed. He was a monk from the Monastery of Saint Anthony, and his mother was also named Yusuf. During his time, many incidents occurred.

(Chapter Twenty) On the Reign of Sultan Mustafa IV, Son of Sultan Abd al-Hamid Following Sultan Selim, his nephew, Sultan Mustafa IV, son of Sultan Abd al-Majid, ascended to the throne. He was enthroned on the eleventh of Rabi' al-Awwal in the year 1282 AH, corresponding to 1867 AD. However, his reign was nominal, with real power held by the Janissaries and their supporters who opposed the new order. They managed all affairs according to their whims, appointed unqualified individuals to positions, and handed over the keys to fortresses and castles to the leaders of the troops who had proclaimed the Sultan. This brought an end to the turmoil, and matters returned to their previous state. News of these events reached the army fighting the Russians. A group of Janissaries rejoiced at their victory and conspired against the Grand Vizier, whom they killed. They appointed Mustafa Pasha as his replacement. Corruption then spread throughout all state affairs, and the ignorant seized control, causing chaos and destruction. Shortly thereafter, the leader of the rebels turned against his own supporters and was replaced by another named Tahir Pasha. Once Tahir Pasha settled into his position and understood the situation, he realized he had no real authority, with the Janissaries and the rebel leaders holding all the power. He abdicated and left Constantinople for the city of Ruse. Near Ruse, Mustafa Pasha, who was eager for the new order and had assembled a large army, was a supporter of Sultan Selim and favored his return to the throne. Tahir Pasha, upon hearing this, had renewed hopes of restoring the Sultan to his throne. He sent a message to the Grand Vizier and the influential figures, urging them to betray the Janissaries and the rebel leaders. He managed to sway them to his side, and they agreed. The Grand Vizier issued an order for the execution of the rebel leader.
