Are you sure about this? One of the Madinah University professors gives a bayaan in Urdu at Masjid an-Nabawi . He is a typical Ahle Hadees guy, without the accusations against Imam Abu Haneefa . He said that Rasoolullah is dead in his grave (نعوذ با الله), saying that he was in the life of barzakh, which is what I've also heard Mamatis believe. According to them, the life of the barzakh is the life of everyone after death, but that there are levels within barzakh. They even believe that the shuhada are in the barzakh but at a higher level. They are not literally alive, according to them. According to Ml. Ilyas Ghuman DB, this is in clear violation of clear indication from the Qur'an that they are alive, not dead - it's just that we cannot sense them. Otherwise, there wouldn't be anything special about them if they're in barzakh like everyone else but just at a higher level and there would be no need in the Qur'an to say that they're alive and to forbid us from saying that they're dead. Furthermore, I've heard many Salafis praising Mamatis over Deobandis, saying that the Mamatis are closer to them. I've never heard this. I do know that the Hizb-ut-Tahrir doesn't believe in punishment in the grave.
