The book is a collection of sermons, precepts, prayers, epistles, and aphorisms of Ali and compiled by al-Radi in the tenth century. A number of his contemporaries wrote commentaries on al-Radi's compilation.
Extent and scope of compilation Ali's sermons were compiled, read, and taught before al-Radi was born. The services of al-Radi are now regarded as significant in the philosophy of
monotheism. Collected sermons in the Nahj al-Balagha cover Islam, theology and metaphysics; worship, wisdom, philosophy; piety and the afterlife. However, critics of the
Nahj al-Balagha generally raise two objections: they claim that al-Murtada is one of the authors, and most of the contents are not by Ali. == Offspring and death ==
