What is the response to those who say that in this land we do not need to emphasize and explain tawhid (the oneness of Allah)?

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the response to those who say that in this land we are people of tawhid (the oneness of Allah) and we do not need to emphasize and explain tawhid?

Answer:
It is a scheme of Satan. We are in this land, and praise be to Allah, upon the creed of tawhid (the oneness of Allah), but we do not consider ourselves perfect, nor do we declare ourselves pure. We may fall into something while we are unaware of it. If we do not learn tawhid, we fall; we fall into things involving shirk (associating partners with Allah) and things that corrupt tawhid because we are ignorant of them. This ignorance is not permissible for us. We learn tawhid, even if we are among the people of tawhid, in order to establish it firmly and so that we do not fall into something we are unaware of. Is anyone more devoted to tawhid than Ibrahim (peace be upon him)? Did he not say in his supplication: So do not be secure from shirk in the land of tawhid. Do not be secure from shirk, and explain the dangers of shirk so that no one falls into it. No one is secure for himself, nor does anyone declare himself pure. Their saying contains a scheme to cause people to abandon tawhid and not give it attention.
