If someone asks me: Are you a believer?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: If someone asks me, "Are you a believer?" Is it permissible for me to say, "I am a believer," meaning that I believe in Allah, His angels, His books, His messengers, the Last Day, and the divine decree, its good and its evil?

Answer:
That is, you are in a land of disbelief, and they do not know that you are a believer or that you are a Muslim. If they ask you, you say, "I am a Muslim," and there is no harm in that. Do not say, "I am a believer." Say, "I am a Muslim," if you are in a land of disbelief. But if you are in the land of the Muslims, there is no need for this question. Yes.
