Thamir is the active participle of thamara, “to bear fruit” (root th-m-r, that of thamar, “fruit”): lexicographers call a tree thamir when its fruit is ripe, and one says thammara malahu, “he made his wealth bear fruit”. The name expresses the wish for a fruitful, prosperous life; it is mostly given in Saudi Arabia, Kuwait and Iraq. Tamir (Tamer), very popular in Egypt and Turkey, is a neighbouring name, explained by tamr, “dates”.
And it is He who sends down rain from the sky, and We produce thereby the growth of all things. We produce from it greenery from which We produce grains arranged in layers. And from the palm trees - of its emerging fruit are clusters hanging low. And [We produce] gardens of grapevines and olives and pomegranates, similar yet varied. Look at [each of] its fruit when it yields and [at] its ripening. Indeed in that are signs for a people who believe.
And He it is who causes gardens to grow, [both] trellised and untrellised, and palm trees and crops of different [kinds of] food and olives and pomegranates, similar and dissimilar. Eat of [each of] its fruit when it yields and give its due [zakāh] on the day of its harvest. And be not excessive. Indeed, He does not like those who commit excess.
