For the purpose of the education of Labbai and Marakkāyar children, the Korān and other books have been published in the Tamil language, but with Arabic characters. Concerning these Arab-Tamil books I gather that "when a book thus written is read, it is hardly possible to say that it is Tamil — it sounds like Arabic, and the guttural sounds of certain words have softened down into Arabic sounds. Certain words, mostly of religious connection, have been introduced, and even words of familiar daily use. For instance, a Labbai would not use the familiar word Annai for brother, Tagappan for father, or Chithammai for aunt, but would call such relatives Bhai, Bava, and Khula. Since the books are written in Arabic characters, they bear a religious aspect. The Labbai considers it a sacred and meritorious duty to publish them, and distribute them gratis among the school-going children. A book so written or printed is called a kitāb, rather than its Tamil equivalent pustagam, and is considered sacred. It commands almost the same respect as the Korān itself, in regard to which it has been commanded 'Touch not with unclean hands.' A book of a religious nature, written or printed in Tamil characters, may be left on the ground, but a kitāb of even secular character will always be placed on a rihal or seat, and, when it falls to the ground, it is kissed and raised to the forehead. The origin of this literature may be traced to Kāyalpatnam, Mēlapālayam, and other important Labbai towns in the Tinnevelly district." The following rendering of the second Kalima will serve as an example of Arab-Tamil.
