The ruling on a voluntary fasting person breaking his fast when invited to a meal

Question:
May Allah reward you with good and do you good. He says: When I am fasting, I visit some friends and they offer me food or drink. Sometimes I oblige them and break my fast, and sometimes I do not eat anything and do not show them the reason, nor do I say that I am fasting. What is the correct way in such a case? May Allah reward you with good.

Answer:
If the fast is voluntary, it is permissible for the person to break it, especially if he is invited. If his brother invites him, he should respond to the invitation. If he wishes, he may break his fast and eat from the food of the invitation. If he wishes, he may continue his fast, and he should make du'a for them, for the people of the invitation, and then leave, informing them that he is fasting. There is no harm in doing so in order to please them and let them know his excuse. There is no showing off in this, praise be to Allah. Praise be to Allah. Because he does not intend showing off by it, but rather he intends to please them and explain the excuse for which he did not eat from their food. Yes?
