Also a tree springing out of Mount Sinai, which produces oil, and relish for those who use it for food.
The tree mentioned here is the olive tree. The Qur’ān mentions it as a tree growing in
the lands around Mount Sinai; Mount Sinai may have been its natural habitat or the place
where the best olives were produced, at least at the time when the verse was revealed.
