I came across a book called "Islamic Geography" by Dan Gibson. The author has presented a thesis based on his research (historical records, archaeological evidence etc.) that Mecca was not the original holy city of Islam - it was the city of Petra instead. Here is a link to the relevant section of the book: http://www.searchformecca.com/Mecca%20Question.pdf Can you look into these claims with academic honesty, and come up with a critique?
I want to understand the arrangement of the verses in the first two groups of the Qur’an, chapters 1 to 9. For example why are the verses related to the battle of Uhd placed in the third surah and the verses related to the battle of Badr placed in the eight surah ? How would the prophet saw communicate the verses revealed in Madina to the people living in Makkah?
