Written originally by Ibn Qayyim al-Jawziyyah is one of the important resources of knowledge for those who seek to know the Seerah of their Prophet as well as the Fiqh learned from it. 

This is a book that is unique in that it explains the Sunnah through the Seerah and the Seerah through the Sunnah.

It is a profound classic work containing thousands of pages written by Imam Ibn al-Qayyim while on the Hajj journey, Pilgrimage, from Damascus to Makkah. Despite its being written from memory, the several thousand incidents, Hadiths, Ayat (verses of the Quran), Fiqh benefits, as well as names of the companions associated with them, were remarkably close to the truth with marginal errors.

However, those who know the status, level of knowledge and Ta'hqiq that Imam Ibn al-Qayyim had will not be surprised to know this fact. Still, it is amazing how Ibn al-Qayyim was able to write this vast volume while traveling to Hajj (Pilgrimage), especially since he was away from the resources of knowledge and was enduring the hardships of travel. It is a blessing from Allah (سبحانه وتعلى) that it was possible for him to do so.

Note: As with many English translations this work appears to be slightly abridged but it seems to cover most of the subjects.
