The importance of knowing Allah and knowing the Prophet (peace and blessings be upon him), and that this is among the three fundamentals

Question:
The third question is about the three fundamentals. May Allah reward you, Shaykh. The Imam Muhammad ibn 'Abd al-Wahhab mentioned the first fundamental, which is knowing Allah (Glorified and Exalted is He), the second fundamental, which is knowing the Prophet (peace and blessings be upon him), and the third fundamental, which is knowing the religion of Islam with evidence. Shaykh, there is a point of confusion: are the first and second fundamentals included within the third fundamental, which is knowing the religion of Islam? Why did the Shaykh (may Allah have mercy on him) exclude them from it?

Answer:
My brother, knowing Allah by His names and attributes, and by His lordship and His divinity, is necessary. This is the head of Islam. And knowing the Prophet (peace and blessings be upon him) is for the sake of following him and taking him as a model (peace and blessings be upon him). Yes.
