Book Year 20, the present volume, covers events from Muharram 1-Dhu al-Hijja 30, 7 AH/ca. May 11, 628 CE-April 30, 629 CE. Each Lesson begins with a critical thinking (furqan) standard, strategy or Quranic moral trait. It is important to note that when learning HOW to think which the Quran teaches, there is no specifically correct answer. It is going through the process of Quranic understanding that we learn HOW to think.

The Timeline places the Messenger’s Campaigns, including the Battle of Khabar and his Umra, his marriages and Patrols that the Messenger commands a Companion to lead.
