This book is one of the most famous works written on this subject. It is one of the important resources of knowledge for those who seek to know the Seerah of the Prophet, may Allah bless him and grant him peace, as well as, the fiqh to be learned from it. It is unique in that it explains the Sunnah through the Seerah and the Seerah through the Sunnah. It is a profound classic work written by Imaam ibn Al-Qayyim while on the hajj journey from Damascus to Makkah. Despite its being written from memory, the several thousand incidents,Qur'anic verses, the Prophet's traditions, fiqh benefits, as well as, names of the Prophet's Companions associated with them, were remarkably close to the truth, with marginal errors.
