The ruling on praying in a mosque built with money from haram (forbidden) sources

Question:
May Allah reward you and bless you. This questioner, Honorable Shaykh, sent a set of questions. The questioner is from Yemen, from Ibb, and he used the initials Kha, 'Ayn, Mīm for his name. He says: To the Honorable Shaykh Salih al-Fawzan (may Allah preserve him), he says: What is the ruling on praying in a mosque where money taken from people without their consent was used in its construction, and what is the solution to this problem? May you be rewarded.

Answer:
Is it not permissible to build mosques with haram (forbidden) money? It is not permissible to use haram (forbidden) money for Muslims, neither for eating nor drinking, nor clothing, nor housing, and a fortiori for mosques, which are the houses of Allah. Indeed, Allah the Exalted is Pure and does not accept except what is pure, and usurped money is haram (forbidden). The saying of the Prophet (peace and blessings be upon him) with the consent of his own soul.
And in His saying, the Exalted, , and if a mosque is built with usurped money, then it is not permissible to pray in it. However, the solution in my view is to look at the usurped money and return it to its owner in its amount, and then pray in the mosque. Yes.
