Book Year 17, the present volume, covers events from Muharram 1-Dhu al-Hijja 29, 4 AH/ca. June 13, 625 CE-June 1, 626 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 Lessons in Book Year 1 through Book Year 24, including Book Year 17 presented here, are numbered consecutively in order of the revelation of a Quranic Chapter. It begins with Lesson 93 and Quranic Chapter 99, the 93rd chapter revealed followed by Quranic Chapters 57, 47, 13, 55, 76, 65, 98 and, finally, Quranic Chapter 59 in Lesson 101. The Timeline places the Messenger’s Campaign, his marriages and Patrols that the Messenger commands a Companion to lead.
