Is it permissible for my mother and mother-in-law to have dinner with me in their mourning period?

Q 3: My father died leaving behind two widows including my mother. My house is almost twenty meters away from theirs. Sometimes, I celebrate some occasions; is it permissible for them to come to have dinner with me? It should be noted that we live in the desert. There are no houses close to us and they are now in their mourning period.

A: If the reality is as mentioned, it will be permissible for them to go to your home and have dinner there. There is nothing wrong with that. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
