Reason for Composing the Book
Because I was unable to find a single, comprehensive work on this subject, I considered it incumbent upon me to present my Muslim brothers—those whose chief concern in worship is to follow the guidance of their Prophet ﷺ—with a book that is, as far as possible, exhaustive on everything connected to the Prophet’s prayer, from the opening takbīr (saying “Allāhu akbar”) to the closing taslīm.
