He took great care to heed his father's lessons, putting aside his personal feelings when dealing with people, friend and foe alike. When forced to deal with a traitor amongst his men, he showed mercy and exiled them despite his desire to see them killed, and when Ozan, the man who saved him, was exiled for his crimes, Ali kept the punishment in place despite his favourable feelings towards him.
During year 169 of the Fifth Age, the then crowned Prince Ali was kidnapped by a criminal group known as The Skulls while touring the neighbouring village of Lumbridge. After being led to Draynor Village by the gang members, he was then handed over to Lady Keli, the commissioner for the kidnapping. This was done in order to use Ali as a form of ransom to obtain the Kharid-ib diamond, a large and powerful gemstone that is of significant importance to the history of Al Kharid. Despite the intervention of Leela, one of Al Kharid's spies, and a pair of adventurers, Ozan and another, Lady Keli managed to take him from Draynor. The trio used the Kharid-ib to track Lady Keli, who revealed herself to be Amascut, then defeated her henchmen Apep and Heru, rescuing the prince. He returned home to find that his father, Emir Shah, had died, and so took over as Emir of Al Kharid.
Later that year, the Pharaoh of Menaphos sent a request to Ali, requesting the resumption of trade between their two cities. He compiled an envoy comprising of Grand Vizier Hassan and the adventurer who had rescued him, sending them to Menaphos.
Later, the adventurer returned to Al Kharid, presenting Osman with a sought after book and gave Ali a report from Hassan. Ambassador Jabari appeared, demanding the return of the book, claiming it had been stolen. He also claimed that Osman had been playing the role of double agent, providing Jabari with information needed to kidnap Ali. Osman protested his intentions while the adventurer went to deal with Jabari. Ali stripped Osman of his position as spymaster and banished him from Al Kharid under pain of death.
^Ali Mirza, "Our Man in the North", RuneScape. "It is taking all of my will right now to not have you executed where you stand, rightful Pharaoh or not... but I listened well to my father's words. You shall not die for these actions."
^Ali Mirza, "Diamond in the Rough", RuneScape. "But I find upon my return that he took the Kharid-ib against my father's wishes, and to rescind my father's last order would be to dishonour him. So, as things stand, Al Kharid must view Ozan as an traitor to be arrested upon sight.[...]In fact, if he were ever to return the Kharid-ib, I would welcome him home as a brother."
^Khnum, "Stolen Hearts", RuneScape. "Fine! There's a staging area directly south of here, on Draynor's coast. My men were to lead them there – there's a boat docked. Once this Lady Keli had the prince safely aboard, we were getting paid and cutting ties."
^Leela, "Stolen Hearts", RuneScape. "Fine! I will trust you... for now. But only because I need information too. Do not think this makes us friends. But you are too late to STOP the kidnapping – the prince went missing while he was touring Lumbridge. I have followed the trail to Draynor."
^Emir Ali Mirza, "The Jack of Spades", RuneScape. "We have received a communication from the Pharaoh of Menaphos.[...]No. Quite the opposite, in fact. In the interests of maintaining the peace, they wish to reopen trade between our cities. To that end, they have invited me to send an envoy to negotiate a deal."
