Is it true that Najd before the call of Shaykh Muhammad ibn 'Abd al-Wahhab did not have the worship of graves?

Question:
He says: Honorable Shaykh, may Allah grant you success, there are some of our own people who doubt the history of Najd before the call of Shaykh Muhammad ibn 'Abd al-Wahhab (may Allah have mercy on him), claiming that it was merely political conflicts, and that Najd was not in the state of worshipping graves at that time. How do we respond to them?

Answer:
This is a known fact. The opponents of the call to tawhid (the oneness of Allah) have existed for a long time, since the time of the Shaykh. They have always disputed with the Shaykh and refuted him. This is evident in the Shaykh's responses to them. Does the Shaykh respond to jinn or to his own desires?
He responds to real people who dispute with him. This is a known fact. The one who denies this denies reality. He denies reality. Furthermore, he lies about the Shaykh and lies about the scholars who mentioned what existed in the time of the Shaykh and before him. He lies about them, meaning he lies about the scholars and betrays them. May Allah keep us safe. He praises people while he does not know about them. Did he live in that society?
But this ignorance, and this desire, and may Allah protect us from it, and this enmity toward tawhid (the oneness of Allah), is enmity toward tawhid and its people, and it is a denial of reality. Yes.
