Shortly after his accession, he ordered the killing of Tun Telanai, the hereditary chief of the neighbouring Terengganu, for, without his knowledge, had visited Melaka and paid obeisance to Sultan Alauddin.[20] In 1488, Sultan Alauddin of Melaka died at Pagoh on the Muar river, poisoned, it was said, by the rulers of Pahang and Indragiri. Nobody could have desired Alauddin's death more eagerly than his elder brother Sultan Ahmad of Pahang who had been passed over for the succession to the Melaka throne by Alauddin. The ruler of Inderagiri implicated in the poisoning must have been Raja Merlang who had married Alauddin's half sister Raja Bakal and settled in Melaka where he died.[21]
