Translation of the verse 20 from Surah Al-Mu’minun : Number of verses 118 - - page 343 - Part 18.
And a tree (olive) that springs forth from Mount Sinai, that grows oil, and (it is a) relish for the eaters.
And [We brought forth] a tree issuing from Mount Sinai which produces oil and food for those who eat.
(23:20) And We created the tree which grows on Mount Sinai: *21 ' it gives oil and is used as food also by those who like to eat it.
*21) That is, the olive-tree, which is the most important product of the lands around the Mediterranean Sea. The olive-tree can last for 2,000 years or so, so much so that some trees in Palestine are said to be existing since the time of Prophet Jesus. It has been attributed to Mount Sinai probably for the reason that the area whose well known and prominent place is Mount Sinai is its original habitat.
