Graves found while digging the foundation of the mosque

Question:
A questioner asks, saying: We are building a mosque in the place of an old mosque. The old one was small, and the village is large, so we wanted the mosque to be big enough to accommodate the people of the village. When we dug the foundation behind the site of the old mosque, we found graves. The elderly people in the village say they do not know the owners of these graves or who is buried in them. What is the ruling? There is no other place to build the mosque on. Please issue a ruling for us. May Allah bless you.

Answer:
It is obligatory for you to stop digging and to write a question to the Department of Ifta, as is customary. This is the current procedure: a question is written about the cemetery where this occurred, or about the graves that were found, and a report is written about them to the Department of Ifta, and they will look into it, if Allah wills. Yes. But stop digging now. Yes.
