Various matters in which there were differing reports that the Prophet gave to his contemporaries and companions. This book collects these various reports and analyzes the real differences and gives proof to what is actually more applicable to which situation versus others, for example; a report on the Fatiha recitation during prayer narrated by Abu Qatada and then not mentioned to an Arab Traveler from the Bedouin. Excellent comparative law book for any level of understanding and easily arranged by subject.
