What is Wahhabism? Who is a wahhabi?
I have never heard or read a single definition exclusively of Wahhabism. I have never come across a single person who claims to be a Wahhabi. I have not seen a single masjid or office or group anywhere in the world which claimed to be a Wahhabi.
Thus, Anybody who uses this term is either totally ignorant or a liar.
Al Wahhab is attribute of Allah SBT meaning Bestower. If someone uses that word means he or she is ridiculing the Almighty.
