There are suspicions that my aunt is involved in سِحْر (siḥr), because she went to a ساحر (sāḥir) to bring back her husband and has said words like "إِرْبِط" and similar things. How should one deal with this, and are there any precautions that can be taken?

Ustadh AbdulAziz al-Haqqan
Don't accuse someone of something when you are not sure, and there is no harm in looking out for yourself and being careful.
