Informing the fasting guest at a wedding feast that he is fasting

Question:
Honorable Shaykh, may Allah grant you success. The questioner says: If a person goes to a wedding feast during the day and is invited to eat, and he is fasting, is it prescribed for him to say, “I am fasting,” or is this considered a form of showing off (riya’)?

Answer:
He does not inform them that he is fasting. He makes du’a for them and tells them that he is fasting and that he attended to please them, then he leaves. This is so that they do not have any negative feelings about him. If they know he is fasting, they will excuse him. But if he leaves without eating, they might have some negative feelings about him. So he removes this by explaining it to them. Yes.
