Malik Al-Sayf

"I know... in fact, the entire city knows!"

- About Altaïr's successful assassination

Malik A-Sayf, previously a high ranking assassin rivalling Altaïr, is the Dai and the leader of the Jerusalem Assassin's Bureau.

Solomon's Temple
Malik, along with his brother Kadar and Altaïr, were charged with capturing the Templar's Treasure, later found to be the Piece of Eden by Al Mualim. He forewarns Altaïr of his blatant disregard of the Creed when Altaïr murders an innocent old man beneath the Temple to hide their presence and considers compromising the Brotherhood for the chance to kill Robert de Sable. Eventually, Altaïr's stubbornness, headstrong attitude, and arrogance leads to the tragic failure of the mission, costing Malik his left arm and his brother's life. Malik however successfully escaped with the Piece of Eden, and arrived at Masyaf with his arm still attached but bleeding badly, implying it was amputated later.

Jerusalem: 1st Visit
When first meeting up with Altaïr in Jerusalem, Malik makes no effort to disguise his new-found hatred of Altaïr. Pointing out even the most subtle of flaws and the small haughtiness of his attitude whenever possible, the two have an unpleasant meeting when discussing the assassination of Talal. Even though the assassination was a success, he criticizes Altaïr for triggering the City Alarm and alerting the citizens of Jerusalem to Talal's demise.

Jerusalem: 2nd Visit
Though his cold attitude toward Altaïr has gone through little to no change, he expresses a small level of satisfaction when Altaïr asks for advice and begins to respect the Creed more. After the assassination, he notes that Altaïr had performed just as an assassin should -- no more, no less.

Jerusalem: 3rd Visit
When Altaïr visits Malik for the final time in Jerusalem, the easily angered and quick to criticize Malik has changed, speaking to Altaïr as a fellow assassin rather than the failure that had caused the tragedy in Solomon's Temple. After the skirmish at the funeral of Majd Addin, Malik and Altaïr have a quick, heated argument over whether to chase Robert de Sable to Arsuf or return to Masyaf to seek the wisdom of Al Mualim. Altaïr argues that Malik uses the Creed as a shield, not seeing the entire truth but rather what Al Mualim wants him to see, and then suggests that Malik learns more of the Piece of Eden from the people of Jerusalem and Al Mualim while he hunts down Robert. Before their departure, Altaïr apologizes for his failure at Solomon's Temple, which Malik refuses because he feels that the Altaïr who stands before him at that moment is not the same one that had sparked their defeat at Solomon's Temple.

Masyaf
Malik makes his final appearance at Masyaf, aiding Altaïr in fending off the hypnotized assassins with loyal assassins still unaffected by the Piece of Eden. He then leads an assault at the back of the fortress, going on advice given from Altaïr as he personally deals with Al Mualim. His final appearance before the end of the Memory Block is in the last cut-scene, where he catches up to Altaïr in time to witness the Piece of Eden display its holographic map of the world.

After Assassin's Creed
At some point after the events of Assassin's Creed, Malik became the "right hand man" of Altaïr while he was the Leader of the Assassins. Altaïr mentions in the first Codex Pages that Malik suggested that he should forget about trying to understand the Piece of Eden and that he should simply lock it away. Altaïr seemingly ignored this advice as shown in later codex entries. His fate is unknown.

Characteristics and personality
Malik is a harsh, yet wise Assassin who dislikes Altaïr due to his skill and rank in the guild, as well his arrogant attitude in the beginning of the game. On your first trip to Jerusalem, if you stay in the beurau before going to your assassination target and lock on to Malik, he will comment on why you have not already left; one of the comments being "Thinking of another great plan, Altair? Like the one back at Solomon's Temple?!" At first, his devotion to the Creed and Al Mualim is unbreakable and undeniable, yet he slowly gains respect for Altaïr as he changes on his quest to redeem himself.

Trivia

 * Malik is the only Assassin seen wearing a similar outfit to Altaïr's in Assassin's Creed. In this outfit, he is also equipped with a Hidden Blade though his ring finger was not cut, probably due to the inaccuracy of the character design.
 * 'A-Sayf' means 'Summer' in Arabic, "Malik" can mean 'Master', 'King' or 'Owner'.
