If you feel they are sincere and want to know the truth and if you are knowledgable and capable of understanding the Quran and sunnah properly in order to call them to sunnah, this is permissible. Otherwise, you must not debate them.

The sufis are trying to tell me what I’m following is incorrect I follow the manhaj of the salaf.and they are making allegation against muhammad bin abdul wahab ra.I have been ignoring them for a while now and I feel like I want to debate them regarding this matter. Should I debate them or not? Please clarify.
