Will it be permissible to bury another mayyit in a grave in which someone was buried years ago?

Answer

As long as the buried mayyit has disintegrated into the soil, it will be permissible to bury any other Muslim in the same grave regardless of who that Muslim was, whether a relative or a stranger, male of female. It is not permissible to bury a Muslim in a non -Muslim graveyard. However, if a non -Muslim was buried in a Muslim graveyard and his body has disintegrated into soil, then while it will be permissible to bury a Muslim in that same grave, it is not advisable. A Muslim conscious of the Deen will never want to be buried in such a grave for perhaps there remain effects of Athaab and la'nat in the kaafir's grave.
