The Ruling on Responding to a Wedding Invitation

Question:
The questioner says: A person says that he invited someone to attend his son's wedding, but the person did not attend. Then, after a while, that person invited me to attend his son's wedding. Is it permissible for me not to attend, or is it obligatory for me to respond to the invitation?

Answer:
It is obligatory for you to respond to the invitation. As for his not attending, perhaps he had an excuse and you are blaming him; perhaps he had an excuse. But even if he had no excuse, he is in the wrong. However, you do not meet his mistake with a similar one. The Prophet (peace and blessings be upon him) made it one of the rights of a Muslim over his brother that if he invites you, you respond to him, unless there is a concern in responding, such as there being something wrong in the place, or wrongdoings in the celebration, and you are unable to forbid them. In that case, you stay away from it. Yes.
