What is this 'Wahdat al-Adyaan'? I have heard about a state of fana called wahdat al-wujood but I have never heard of this term, wahdatul adyaan or co

Answer

There is no such concept as 'wahdatul adyaan' in Islam. This is a concept of kufr and shirk of deviates. It is slanderous to attribute this kufr idea to the Sufiya (Auliya). Deviates have deliberately misinterpreted ambiguous statements of some Sufiya who had made seemingly un-Islamic statements during states of ecstasy. Any such statements which are in conflict with the Shariah are set aside or given a suitable interpretation to bring them in line with the Shariah. Some of the statements of ostensible kufr have also been falsely ascribed to the Sufiya.
