You have entered dubious ground by declaring kufr so easily especially when there is a lot of discussion about tawassul. Tawassul is merely a means absolutely no body worships a shaykh or anyone other than allah
You really shouldn't make takfir so easily especially when you can be shown to be wrong
why do you guys conflate Tawassul which is halal to asking dead saints for help? why are you guys so keen and defensive about asking the dead ? I don’t get it.These 'grave worshippers' really only exist as ghost stories I've never come across or heard of one.
