As one can see, all of Ibn ʿAbd al-Wahhāb’s departures from Ibn Taymiyya and Ibn al-Qayyim were in a more radical direction. The most significant of these was his more expansive approach to takfīr, which had implications for ʿadāwa and jihād as well. The unhindered practice of takfīr meant that Ibn ʿAbd al-Wahhāb, unlike Ibn Taymiyya and Ibn al-Qayyim, judged vast swaths of professed Muslims to be unbelievers, and this allowed him to brandish ʿadāwa and jihād at a much wider set of targets than Ibn Taymiyya and Ibn al-Qayyim ever did.
