Sufism 6item Who are the Sufis? What's the rule regarding Sufism? Is it prohibited? Are there echoes of Mysticism or Tasawof in the Nahjul-Balaghah? Have Mystics throughout time referred to the Nahjul-Balaghah for guidance regarding spiritual purification or other Mysticism related issues? What is Sufism? Was Imam Khomeini (r.a) a Sufi? What is the Shiah opinion regarding Sufism and can a Muslim study a Sufi text? Salaam un Alaikum, It is learnt that according to Ahmad Sirhindi, a non shia, Prophet Muhammad (s.a.w.s.) "possessed during his life time two individuations, the bodily human and the spiritual angelic, symbolised in the two M (meem) of his name" and thus "by the end of one millenium the bodily manifestation had completely disappeared and the first M (meem) was replaced by Alif, in Islamic letter mysticism the symbol of Uluhiyyat (Divinity)" and thus "Muhammad became Ahmad" (Muhammad Ahmad shud). We want to know what is this concept of Alif and Meem and how Muhammad became Ahmad and what is the Shia belief in this regard as what we know that Prophet (s.a.w.s.) name was Muhammad but he had been mentioned in previous scriptures as Ahmad. Jazakallah, Was-salaam.
