I want to marry a sunnī salafī girl who says that her father performs and deals with magic. So what is your advice for me in this regard and how should I interact with her father if I do marry her?

Shaykh Ṣāliḥ ibn Fawzān al-Fawzān:

Stay away from her. Stay away from her. Allah ﷻ will provide you with someone else.
