http://www.central-mosque.com/fiqh/alive.htm Shaykh (Mufti) Ibraheem Desai (HA) says: The question that now arises is, what is the meaning of them being alive? Mufti Shafi (RA) commentating on this verse in his Ma’ariful Qur’aan explains, ‘It is well known that from the Islamic viewpoint, every dead person has a special type of life in Barzakh through which he experiences either punishment or enjoyment. However, there are different levels in this life. There is the level which is general for all, and there are special levels for the Ambiyaa, the martyrs and the pious. With regards to the reality of those levels, the best explanation is given by Moulana Ashraf Ali Thanwi (RA) in his Bayaanul Qur’aan. Shaykh (Mufti) Nawalur-Rahmaan (HA) also says the same in Urdu: http://www.shariahboard.net/ In fact he says that those who believe that Rasul-ullah is alive in real life are "absurd" because they should dig him out of the grave. Most Ulama in the West believe that Rasul-ullah is alive in Barzakh and I don't know what Hayati/Mamati business is but take it up with Shaykh (Mufti) Ibraheem Desai (HA) and other Deobandi Ulama.
