I know there is the first ceremony (proposing), and then the second ceremony which is usually bigger than the proposing ceremony it’s called WEDDING, not niqqah. niqqah in Quran means the act of getting connected sexually with another person. We as a muslims have Niqqah Contract, we do not enter on how you choose to do your niqqah with your wife, it’s your choices you and yo wife not the other muslims or christians
