The original name of Sultan Muzaffar Shah is Raja Kassim[1]: 246 and known as Sulutan Wudafona Sha (苏丹慕扎法沙) in History of Ming of China.
His uncle, Tun Ali was an influential Tamil Muslim leader who allegedly conspired to assassinate the fourth sultan of Malacca, Raja Sri Parameswara Dewa Shah so that his nephew could ascend the throne.
Sultan Muzaffar Shah ordered his senior officers to perform all the customs, traditions and prohibitions introduced by his late father.
Sultan Muzaffar Shah married the daughter of the Bendahara (Prime Minister) and had a son named Raja Abdullah.
When the Malacca government learned about this plan, it prepared its naval and decided to attack the Siamese in Batu Pahat.
Seeing that the feud between these two powerful leaders can lead to disunity among the people of Malacca, Muzaffar decided to level with Tun Ali, who was a middle-aged widower at the time.
