Concerning the Affirmation of Divine Oneness (Risala fi't-Tawhid)http://www.ikitab.com/index.php3?
By Shaykh Wali Raslan ad-Damishqi
Shaikh Wali Raslan ad-Damashqi was one of those Shaikhs who extoiled the greatness of Shaikh Abd al-Qadir al-Jilani (may Allah be pleased with them both). He spent most of his earthly life in the Syrian city of Damascus and passed onto Allah's mercy ca. AH 540/1145 CE.
This is one of the most original books written on the science of Divine Unity (ilm at-Tawhid), and the most comprehensive teatment of the subject within such a small space. This book also contains the commentaries of Shaikh Wali Raslan's work by Shaikh Zakariyya al-Ansari (d AH 926) and Shaikh Ali b. Atiyya Alawan al-Hamawi (d AH 936).
Translated by Muhtar Holland, one of the foremost translators of classical Arabic, Concerning the Affirmation of Divine Oneness is a work of great value to every English-speaking Muslim.
