This book is a compilation of 40 of the finest sermons of the Prophet Muhammad, which in the words of the translator, Assad Nimer Busool, “carries the fragrance of the breath of the noble Prophet.” According to Abu Nasr Muhammad ibn Wadan, the collector of these prophetic sermons, he was fully satisfied about their authenticity because of the reliability of the chain of transmitters (Isnad) of these Hadiths, and the soundness of the testimonies of the teachers and students who had studied them. This collection has a commentary on it in the Zahiriyah Library of Damascus.
