Can a nikah be done during a woman's period?

In Islam, the nikah is a contractual agreement, and most scholars say it is valid during a woman's period. Menstruation affects certain acts of worship, like prayer and fasting, but it does not invalidate a marriage contract. Some communities or individual scholars may have their own views, so it is wise to ask the imam or the person conducting your nikah for their guidance. If you are planning the date, you can simply go ahead, but if you or your family feel more comfortable waiting, that is also fine. The key is that the marriage is legally and religiously valid. In the UK, the nikah alone may not be legally binding in England and Wales unless it takes place in a registered building with an authorised person. Many couples add a short civil ceremony to ensure the marriage is recognised by law. Check with your place of worship and the local register office about what is needed. This is a personal and spiritual matter, so do what brings you peace.
