The ruling on saying that the creed of Muslims and Christians is one

Question:
May Allah reward you. The questioner asks: What is the ruling on one who says, "Our creed and the creed of the Christians are one," for the sake of political interests?

Answer:
I seek refuge in Allah from such speech. Our creed and the creed of the Christians are not one. The creed of tawhid (the oneness of Allah) and the religion of Ibrahim are not like the creed of the Trinity. We ask Allah for safety from this, for the sake of this world and for the sake of interests. No, this is not permissible. This is not permissible. Yes. It is permissible for us to deal with them and to make treaties with them in matters that secure our religion, prevent them from causing us harm, and keep their evil away from us. A treaty is a reality, and the Messenger (peace and blessings be upon him) did it. But to be satisfied with their religion or to praise their religion, this is not permissible. This is kufr (disbelief) against Allah the Exalted. Yes.
