Prayer: Can One Make a Will to Be Buried Inside or in the Yard of a Masjid?

English:

Question #405:

Is it permissible for me to make a will that I should be buried in the local masjid to which I have made many contributions? That is because I would like to be buried in that masjid, whether inside or in its yard.

Answer #405:

If the burial of a dead is not excepted at the time of pronouncing the formula of the endowment, it is not permissible to bury anybody there, and therefore, your will in this regard has no validity.
