The ruling on praying in a mosque built with forbidden funds
Machine translationRead the Arabic original
Question:
A man bought a place with riba (usury or interest) to convert it into a mosque. Is it permissible to pray in it? Also, some of the funds used for it are haram (forbidden), such as the value of khamr (intoxicants). Is the prayer valid in this mosque?
Answer:
The prayer in it is valid, but it is not permissible to use such funds for mosques. One must select good funds for it. If good funds are available, it is obligatory to do so. Otherwise, the prayer is valid, but it is not permissible to build it with funds from riba (usury or interest) or from zina (unlawful sexual intercourse).
