Is it true that Ibn Taymiyyah was appointed a judge by the Mamluks, and that he was a "state mufti," and that the title "Shaykh al-Islam" was equivalent to other titles, and that he resided in palaces?

What the questioner heard about Ibn Taymiyyah, concerning his assumption of judicial office in Sham and his residence in palaces, is a clear falsehood. The Shaykh al-Islam never held judicial office, nor did he reside in palaces. Rather, he was imprisoned multiple times in Egypt and Sham, and he died while in prison. Even his adversaries attested to his asceticism, piety, knowledge, and courage, and that he spoke the truth, fearing no blame from anyone regarding Allah. We advise the questioner to refer to reliable biographical works to verify the biography of Shaykh al-Islam Ibn Taymiyyah.
