Answered by Shaykh Faraz Rabbani
But what about ‘wasiyya’. This is a means for a non-Muslim to give to a Muslim and vice versa isn’t it. For example, in the non – Muslims will, he writes that so-and-so should be given such – and – such. Isn’t this permissible. I know its not called inheritance
It is valid to take a bequest from a non-Muslim parent, if they specified it, even though a Muslim does not inherit from a non-Muslim.
