Taufa Ithna Ashari (Urdu: تحفة اثنا عشرية) (Gift of Twelvers) by Shah Abdul Aziz: Its the great book originally written in Perisan, on Shia Belifs and practices. This is an authority on the subject rarely available in the market.
Shah Abdul Aziz was the eldest son of Shah Waliullah was only 17 years old when Shah Waliullah died. He took over as the teacher of Hadith in place of his father, and later became famous as the Muhaddith of Delhi (just like his father) and one of India's greatest Islamic scholars. In this book, he has described the history, belief and teachings of the Shia’s. There was hardly any Suni house, he says, in which some of its members had not become Shia. They did not know anything about their new faith, or even concerning Sunnism. Therefore, the author, as he says, compiled the book, to provide information to people who were really interested in such debates.
