Dr Saab has presented a thinking man's interpretation of the verses on fig and olives, so we do not have to put Muhammad in Syria or Petra.
Dr Saab could be wrong, always ready and willing to advance our understanding of the Qur'an with increasing knowledge, but Petra etc are definitely wrong.
Surah 95. At-Teen – The Fig
[Author’s Note] This is the 95th Surah of the Qur’an. It has 8 verses. God presents here four things as evidence to the truth and the unanimity of His messages. The Fig, the Olive, the Mount Sinai and the town of Makkah.
The last two being places, the first two infer as places as well. During the times of the Qur’an’s revelation, Syria and Palestine were the top producers of fig and olive. And that is where the chain of ‘ISBAT’ or the Israelite Prophets of the Tribes and their ancestor Prophets had lived. The last one of them was Jesus, son of Mary.
Therefore, the first three verses of this Surah are connecting Muhammad (S), the last Apostle of God, with the previous links in one blessed chain of Divine revelation.
[“Noah’s Ark came to rest at Judea, in the hills of Ararat, east of the Tigris River. The Valley of Mount Ararat was also known as ‘The Valley of Figs’.” (Monographs of W.W. Hunter 1878, the British author of “The Indian Musalmans”]
Olive is symbolically mentioned in the Qur’an, 23:20, 24:35. Jesus Christ delivered his classic “Sermon on the Mount” at the Mount of Olives just outside the walls of Jerusalem. [Mathew 24:3-4]
Fig is figuratively mentioned in Mathew 21:18-20, 24:32-35 and in Jeremiah 24:1-10.
With the Glorious Name of God, the Instant and Sustaining Source of all Mercy and Kindness
95:1 Witnesses are the Valley of Fig (alluding to Noah) and the Valley of Olive (alluding to Jesus). [The call of these messengers, the places and the reaction of their people]
95:2 And Mount Sinai (alluding to Moses). [19:52, 20:9-36, 52:1. Exodus 3:1-18 and 4:1-17]
95:3 And now, (O Messenger) this land of security and peace. [Makkah where the Final revelation has begun. 2:126]
95:4 Indeed, We have created the human being in the best design (and with the potential to grow the ‘self’.)
95:5 Then We turn him to the lowest of low. [Whoever rejects Permanent Values, reduces himself to a subhuman existence. 91:7-10]
95:6 Except those who choose to be graced with belief, and work to increase the human potential - theirs is a reward unending.
95:7 What, then, can make you deny the Divine System and the Final Judgment?
95:8 Is not God the Sovereign of the sovereigns, the Wisest of the wise, the Best of all judges? [Hukm carries all three meanings]
