Book Year 18, the present volume, covers events from Muharram 1-Dhu al-Hijja 30, 5 AH/ca. June 2, 626 CE-May 22, 627 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. Book Year 18 presented includes Quranic Chapter 24 as the 102nd chapter revealed so the lessons are Lesson 102. The Timeline places the Messenger’s Campaigns, including the Battle of the Trench, his marriages and Patrols that the Messenger commands a Companion to lead.
