Mamati ceased to be Deobandi since the Shaykh joined the Salafis? Just search for "Hayati mamati" on this forum and you will find out many hardcore Mamatis here as well , Colonel_hardstone happens to be one though he does not like labeling himself a mamati Deobandi. Shaykh Abdul Hay Lukhnavi Deobandi also happened to be a mamati ie who believes that Sayyidna Muhammad sws is alive in Barzakh not in his grave in Madina , unlike the hayati Deobandis who believe that Sayyidna Muhammad sws is alive in his grave as he was alive in this world and he hears the Sallam which is offered at his grave by himself and responds back.
