Is it permissible to attend the wedding of a Christian in a church? Do they have the rights of a neighbor like a Muslim? What is a summary of the dealings with the People of the Book (Ahl al-Dhimma)?

The ruling regarding accepting an invitation to a feast from a non-Muslim and its conditions has been previously mentioned. As for a non-Muslim neighbor, he does not have the same rights of neighborhood as a Muslim. However, he does have a lesser right. People in neighborly relations are of categories: a Muslim close relative has three rights; a Muslim who is not a close relative has two rights; a disbeliever who is a close relative has two rights; and a disbeliever who is not a close relative has one right. For further details on the rulings concerning Ahl al-Dhimmah (People of the Covenant), one should refer to books of Fiqh (Islamic jurisprudence) or Ibn al-Qayyim's book "Ahkam Ahl al-Dhimmah."
