Is it possible that I can get Muslim certificate...

We would like to inform you that if you want to obtain a certificate to convert to Islam in UAE or a certificate showing the religion of the Muslim and non-Muslim, it is in the event that the marriage is Islamic from the Islamic Court
The marriage contract is concluded in front of that court as it’s the base.
For non-Muslims, the certificate can be obtained from the embassy of your state and the marriage is concluded in front of it or in front of the church for lack of jurisdiction by the court in this case.
