What is said to one who does not recognize contemporary scholars such as Al-Uthaymeen, Ibn Baz, and Al-Albani, and claims that they are Wahhabis who follow a new sect?

A Muslim must accept and act upon the teachings of Islam, prioritizing what is in the Qur'an and Sunnah over all else, and measuring people's statements against religious evidence. The call of Sheikh Muhammad ibn Abd al-Wahhab was to Tawhid (monotheism), and he authored "Kitab al-Tawhid" (The Book of Monotheism) based on Qur'anic verses and authentic hadiths. His adversaries could not refute his proofs; instead, they attributed lies to him. Scholars like Ibn Baz and Al-Albani followed the methodology of the Companions, the Tabi'un (successors), and the four Imams. Whoever does not acknowledge them, it is due to ignorance, blind following, envy, stubbornness, following whims, or adherence to innovations. Scholars have refuted them, so one must follow the evidence and prioritize it over anyone's statement.
