Did Imam Ibn Qayyim al-Jawziyya die a violent death due to torture at the hands of deviant sects, and what is the story of his death?

Ibn al-Qayyim suffered greatly from harm, tribulation, and trials at the hands of the people of innovation and the bigots of the madhhabs. He was tested and harmed multiple times, and was imprisoned with his shaykh Ibn Taymiyyah in the Citadel. However, it is not mentioned that the cause of his death was torture, nor is this reported in biographical texts. Had it been true, it would have been mentioned due to the gravity of the news, just as it was mentioned that Ibn Taymiyyah died in his prison.
