Allah Almighty says;
قل سيروا في الارض ثم انظروا كيف كان عاقبة المكذبين
6:11 Say, “Travel through the earth taking lessons from history (in order to comprehend the Laws of the Rise and Fall of nations), and notice the end of those who belied these Laws.”
Prophet Muhammad SAW told people to explore history to "learn" and "understand" the "Truth". How can Muslim learn the history of Islam without looking back?
History can only be known through the "facts" recorded in past and "not" because of what our ancesstors have been beleiveing or practising blindly. Dr. Shabbir's book is an asset to learn about the "facts". A thoughtful comparison of the Hadith and the hsitory with respect to the Quran, can guide us to the Truth.
