In the book Allah  The Unique Name of God the 
                  author, Maulana Abdul Haq Vidyarthi, reviews the names of God 
                  used among the various nations of the world in more than 150 
                  languages and shows that, while each name may express some particular 
                  attribute of God, it is the name Allah used in Islam 
                  that stands out as encompassing all the Divine attributes, being 
                  the personal name rather than an attributive one. There is a 
                  detailed discussion on the names of God in Jewish and Christian 
                  scriptures. The famous expression of the Quran universally uttered 
                  by Muslims, “In the name of Allah” (bismillah), 
                  is shown to be a fulfilment of the prophecies and expectations 
                  of earlier religions.

About the author
                Maulana Abdul Haq Vidyarthi (1888–1977), who bore the 
                  title vidyarthi due to his extensive knowledge of the 
                  Hindu Vedas, was a scholar of the major religions of the world 
                  and their languages, and a missionary of Islam of the Lahore 
                  Ahmadiyya Movement. The environment of multi-faith debate and 
                  discussion, prevailing in the Indian subcontinent in his younger 
                  days, greatly influenced and interested him. This was one reason 
                  why, in 1907, he joined the Ahmadiyya Movement at the hands 
                  of its Founder, Hazrat Mirza Ghulam Ahmad, as this Movement 
                  had a broad, universalistic outlook towards other religions, 
                  regarding all of them as originally revealed, a fact first disclosed 
                  by Islam. 
                
In 1914, when the Ahmadiyya Anjuman Isha‘at Islam 
                  was founded in Lahore by Maulana Muhammad Ali and his associates, 
                  Maulana Abdul Haq Vidyarthi joined this Muslim missionary society, 
                  in which he worked for the rest of his life as missionary, journalist, 
                  lecturer, writer and scholar. First he mastered the Hindu scriptures 
                  and studied the Sanskrit language. Later on, he studied Hebrew 
                  and other ancient languages of world scriptures. His purpose 
                  was two-fold: (1) to be better equipped to refute the storm 
                  of criticism and vituperative allegations against Islam and 
                  the Prophet Muhammad by the Hindu Arya Samaj sect as well as 
                  Christian proselytisers; (2) to unearth prophecies about the 
                  coming of the Holy Prophet Muhammad which, according to Islam, 
                  are to be found in previously-revealed scriptures.
                
In the period 1918 to the 1940s, the Maulana was frequently 
                  called upon, by various Muslim organizations throughout India, 
                  to represent Islam in public debates against Arya Samaj Hindus 
                  and Christian missionaries. He achieved supreme triumph in these 
                  debates, and his name became renowned and legendary. He also 
                  wrote several Urdu books in response to the Arya and Christian 
                  objections against Islam. As a purely scholarly work, he published 
                  an Urdu translation of part of a Hindu scripture, the Yajur 
                  Veda.
                
After the founding of Pakistan and the ending of the multi-faith 
                  environment, the Maulana toured the countries of Trinidad, Guyana, 
                  Suriname, and Fiji during the 1950s at the invitation of the 
                  local Muslim communities, and gave lectures to large multi-faith 
                  audiences, achieving fame and renown for his knowledge and noble 
                  character in those countries as well. He also spent time in 
                  the U.S.A. during 1959-1962, collecting further material of 
                  the kind presented in this book from reference works in libraries.
                
 He originally wrote Muhammad in World Scriptures in 
                  Urdu as Mithaq-un-nabiyyin, published in 1936. Then he 
                  had it translated into English and it appeared under this title 
                  in 1940. A little later he published a second part in Urdu. 
                  He then went on to expand the English version considerably, 
                  which was published in 3 volumes between 1966 and 1975. The 
                  present book, Allah — The Unique Name of God, is 
                  derived from it, as explained in the Preface.
                
Maulana Abdul Haq Vidyarthi was renowned and respected not 
                  only as a man of the highest learning and scholarship, but also 
                  as one who was thoroughly upright and saintly, and a recipient 
                  of extensive spiritual experiences. Having a humble and unassuming 
                  nature, and well-known for his good humour, Maulana Vidyarthi 
                  served the cause of Islam by pen, speech and personal example 
                  for more than sixty years in a unique and rare way which will 
                  have its own place in the history of religion.
