Allah-Upanishad or Allopanishad is a Sanskrit apocryphal text with many Arabic words generally argued and believed to be written in India in 16th century during the reign of the Mughal emperor Akbar.[1] [2] It describes Akbar as a messenger or prophet of God.[3] Critics generally have not seen or studied the scriptures. The word Allah is being used in the sanskrit to denote the Shakti or devi or female aspect of the god. It is mainly used in the tantric scriptures of devi worship. Hum is a bija mantra and is attached to the word Allah and forms Allahumma. In short Allah Upanishad is a tantric scripture for devi worship.
The Allopanishad was the importance part of upnishad until 19th century. After 19th century scholars denied Allopanishad as part of the Upanishad canon, traditionally containing 108 Upanishads, and does not appear in any Vedas. In an issue of The Theosophist, R. Ananthakrishna Sastri wrote that the work was written by Pandits for monetary rewards during the time of Muslim rule in India. He further remarked that the work was not in the style of ordinary Upanishads and its words appear to sound more like Arabic. Jogendra Nath Bhattacharya and B. K. Sarkar categorize Allopanishad as an Islamic Work and write that it was written by a Hindu courtier of Akbar, as an apocryphal chapter of the Atharvaveda. Swami Vivekananda said, "I have been told that Allopnishad was written during the reign of Akbar, to bring the Hindus and Mahommedans together, and sometimes they got hold of some word, as Allah, or Illa in the Samhitas, and made an Upanishad on it. So in this Allopanishad, Mahomet is the Rajasulla, whatever that may mean."

Charles Eliot suggested that the work may have been written in connection with the Din-i-Ilahi movement, and wrote that the work can hardly be described as other than a forgery.[3] Author S. N. Sadasivan says, "When emperor Akbar was toying the idea with new religion Din-i Ilahi, the Brahmins had written for him a new upanishad called "Allopanishad" (upanishad of Allah) which strangely was not acceptable for him".[5] Swami Vivekananda wrote that Allopanishad was evidently of a much later date and that he was told that it was written in the reign of Akbar to bring Hindus and Muslims together.[6] Sadasivan writes that it was written by Brahmins for Akbar when he was experimenting with a new religion.[7] Debendranath Tagore wrote in his autobiography that Allopanishad was composed in the days of Akbar with the objective of converting Hindus into Muslims.[8] Bankim Chandra Chattopadhyay wrote that the Allopanishad was the shameless production of some brahmin sycophant of Muslim rulers of India.[9] Abraham Eraly states that the book was symbolic of the various cross-cultural pollination between Hindu and Muslim cultures during the time of the Mughals and was meant to bring the two communities together.[10]
