Role of wind.
Pollination is the transfer of pollen from the male part of a plant to the female part. Pollinating agents are insects, animals, water and wind. Some plant species even rely solely on wind for pollination.
Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. Almost all gymnosperms are anemophilous, as are many plants in the order Poales, including grasses, sedges and rushes. Other common anemophilous plants are oaks, sweet chestnuts, alders and members of the family Juglandaceae (hickory or walnut family).

Wind plays an important role in pollination. This was known recently, however this was portrayed in the Quran 1400 years ago.
[Quran 15:22] And We sent the seeding winds, then cause the rain to descend from the sky, and gave you water to drink, though you are not the guardians of its stores.
Today we know that wind plays an important role in pollination.
How could an illiterate man who lived 1400 years ago have known about wind pollination?
