Is it possible to clarify the issues in which Ibn Taymiyyah deviated from the scholarly consensus—as mentioned by Al-Hafiz Al-Iraqi, Ibn Tulun, and Al-Ala'i regarding more than 60 fundamental and secondary issues—or to mention the most famous among them and point to a specialized book that compiles and elaborates on them?

The questioner previously mentioned some claims asserting that Ibn Taymiyyah deviated from the consensus (ijma'), and the answer to that can be found in Fatwa no. 61538.

What the questioner seeks is not appropriate for a fatwa; therefore, it is referred to the book "Allegations of Opponents of Sheikh Al-Islam Ibn Taymiyyah: Presentation and Critique" by Dr. Abdullah bin Salih Al-Ghusn, as well as the book "Jalaa' Al-Aynayn fi Muhakamat Al-Ahmadayn" by العلامة Al-Alusi, which discusses and refutes the criticisms of Ibn Hajar Al-Haytami against Ibn Taymiyyah. One can also refer to Fatwa numbers: 150710, 0, and 107623.
