Sultan Ali Mughayar Syah was allegedly poisoned by his wife, Sitt Hur, however there is no indication that Salahuddin was involved in this.
[3] Salahuddin's father Sultan Ali had been engaged in violent conflicts against the Portuguese in Melaka.
However, in September 1537 an Acehnese fleet appeared before Melaka, carrying a standing regiment of around 3,000 men.
The much later chronicle Bustanus Salatin (c. 1640) alleges that Salahuddin lived for nine years after his deposition until his death in 1548.
Alauddin arrived to the capital from Samudra Pasai with an entourage of 200 men, ostensibly to visit his father's grave.
They told the palace guards that Samudra had been unexpectedly attacked by soldiers from Aru (approximately the later Deli Sultanate).
