Aqeedatut Tahawi by Imam Tahawi  Maulana Qari Muhammad Tayy 

Aqeedah Tahawiyya with Commentary by Maulana Qari Muhammad Tayyab. English Translation by Mufti Afzal Hoosen Elias.

Imam Tahawi's al-Aqidah, representative of the viewpoint of ahl-al-Sunnah wal-Jama'ah, has long been the most widely acclaimed, and indeed indispensable, reference-work on Muslim beliefs. Being a text on Islamic doctrines, this work draws heavily on arguments set forth in the Holy Qur'an and Sunnah. Likewise, the arguments advanced in refuting the views of sects that have deviated from the Sunnah are also taken from the Holy Qur'an and Sunnah.
