Is it required to eat if one attends a wedding feast?

Question : You heard his question: Is it required to eat if one attends a wedding feast, or not?

Answer : If we say that eating is not obligatory, that is problematic. Consider this man: suppose he serves the food and says, "Friends, please, may Allah reward you for attending your brother's feast," and you say, "In the safety of Allah, we are not obligated to eat," and you leave his food. It would be more distressing for him if they did not attend at all than for him to say, "Please," and for them to reply, "By Allah, we are not obligated to eat, in the safety of Allah." This would raise many questions about him, and this man might even be accused of earning haram (forbidden) income, or that his wealth is haram, or that he stole this money, or something similar. Now, if we say that eating is obligatory for everyone, that also causes some embarrassment, meaning some people might be fasting, or might not feel like eating, or something like that. Yes.
If we say that it is a collective obligation (fard kifayah), that would be a sound opinion. If those who suffice the requirement approach the food, and one or two people are unable to do so, there is no blame on them. However, to say that eating is not obligatory, as appears from the general statement of the jurists (may Allah have mercy on them), is questionable. Rather, we say: Why did this man go to the trouble?
He went to the trouble to show you that his effort is sincere; he does not go to the trouble for you except to honor you with his food. For this reason, the Prophet (peace and blessings be upon him) called food "takhrimah" (an act of honor), and said: "No one is to sit in his house on his takhrimah without his permission."
