Is it permissible to exhume the grave of a Muslim who was buried in the graves of the disbelievers in order to transfer him to the Muslim graves?

Question:
The guardian of my mother, who passed away in America, buried her in the graves of the Christians there because there was no Muslim cemetery at that time. Now a cemetery for Muslims has been established. So, should she be transferred from the Christian cemetery and placed in the Muslim cemetery?

Answer:
Yes, the grave is opened and the body is transferred, along with whatever is required regarding its care and traces, to the Muslim cemetery. If, for example, the grave is opened and you see it in a place near the houses of the disbelievers, you build it up and ask the earth to cover it so that it is not needed, so that the Christians and disbelievers do not find it. It is absolutely not permissible to be ignorant with the disbelievers. However, if it is a cemetery for Muslims, you bury the Muslims there, and you open the previous grave and transfer the body. If there is no cemetery for Muslims here, you look for a place far from the roads, bury her there, and mark its location so that it is not found or opened.
