The Year 10 of the Revelation Muharram 1-Dhu al-Hijja 29, 4 BH ca. August 29, 618 CE-August 17, 619 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 10 presented here, are numbered consecutively in order of the revelation of a Quranic Chapter. Here, in Book Year 10, we begin with Lesson 69, that is, Quran Chapter 18 which is the 69th Chapter revealed followed by Quranic Chapters 18 and, finally, Quranic Chapter 16, the 70th Chapter revealed. The chronological order of the chapters of the Quran that follow throughout the series is based on the list accepted by al-Azhar University in Cairo and is considered to be the official order. It differs greatly from the chronological order developed by Western scholars over the centuries and is much more detailed. Quranic signs or verses (ayat) of each section (ruku) in a particular Quranic chapter are given in each lesson followed by a commentary. A short paragraph describes the Eight Elements of Reason and then a paragraph titled Example of How Quranic Critical Thinking Works. The paragraph that comes after this is for the student to determine which of the statements are one of the Eight Elements of Reasoning. Each Lesson ends with a Student Self-assessment. An interlude describes the end of the economic scanctions against the Hashim clan of the Messenger, the deaths of Khadija and Abu Talib in Ramadan in this year as well as the Messenger’s visit to Taif and return to Makkah where he marries Sawda and is betrothed to Ayisha. Appendix 1 correlates the original Quranic chapters with their chronological order.
