What advice is there for my brother who wants to marry a Salafi woman?

Answer

The marriage is valid, but will be very problematical. With a salafi wife, your brother will most certainly be confronted with many problems. There will not be munaasabat (compatibility). Salafi women are generally obstinate in their opinions and practices. The differences between salafis and Hanafis are many. Marriage with her is not advisable.
