The principle of excusing one another in matters of disagreement

Question:
Honorable Shaykh, may Allah grant you success. He says: There are those who say that Muslims and Islamic minorities in the West should not speak about misguided groups, and that we should look at what we agree upon and excuse one another in what we disagree upon. They say that if we spoke about them, it would cause division and drive disbelievers away. Is their statement correct?

Answer:
This is a famous phrase attributed to Sayyid Hasan al-Banna. I think it is found in his books. This is a mistake. What did we disagree about? If the disagreement is in creed, it is not permissible for us to excuse one another in creed. This is the general case: the disagreement between us and them is in creed. As for disagreement in matters other than creed, there may be some leniency in that. But disagreement in creed is not acceptable, and we do not excuse one another in it. This is not permissible.
