The ruling on accepting money from a Christian to contribute to the construction of a mosque

Question:
He says: Honorable Shaykh, may Allah grant you success, a Christian man wants to contribute to the construction of a mosque. Is it permissible to accept this money and use it to help build this mosque?

Answer:
There is nothing wrong with that, if it is from lawful money that is taken from him, whether he is a Christian or a disbeliever. If it is from lawful money, there is nothing wrong with it. The Quraysh built the Ka'bah. The Quraysh in the pre-Islamic age of ignorance built the Ka'bah, but they chose good money for it when their funds ran short. So they built it in the state it is in now. They demolished a part of it called al-Hatim, which is called the Stone of Isma'il. This was when their funds ran short, and they were disbelievers. This indicates that if a disbeliever does good, if he does good, it is accepted from him. Yes.
