And it is He who spread out the earth, and set thereon mountains standing firm and (flowing) rivers: and fruit of every kind He made in pairs, two and two: He draweth the night as a veil o'er the Day. Behold, verily in these things there are signs for those who consider!
This verse explains that God made fruits (plants) that have male and female have also human. It had never known yet by the ancient people. But now it can be evidenced by people who have field of vegetation. This indirectly proves that the Al-Quran is not the words of the Prophet Muhammad, even it is a revelation from Allah.
Quran Sura Al-Hijr :22
"And We send the fecundating winds, then cause the rain to descend from the sky, therewith providing you with water (in abundance), though you are not the guardians of its stores. This verse explains that God made the plants that have male and females and how to explain the occurrence of marriage between male flowers and female flowers on the plants."
Plant As A Sourch
In Quran have stated that the fruits (plants) as a source of sustenance which God has given to people and animal for their life.
Quran Sura Al-Baqarah : 22
Who has made the earth your couch, and the heavens your canopy; and sent down rain from the heavens; and brought forth therewith Fruits for your sustenance; then set not up rivals unto Allah when ye know (the truth).
This verse states that God has given man all for the man himself. He has also been created to grow - plants (fruits) that we can use for our source and income. So it is not fair if we make our God except Allah The Almighty Creator.
Quran Sura ‘Abasa : 24-32
Then let man look at his food, (and how We provide it); For that We pour forth water in undance; And We split the earth in fragments; And produce therein corn; And Grapes and nutritious plants; And Olives and Dates; And enclosed Gardens, dense with lofty trees; And fruits and fodder; For use and convenience to you and your cattle.
This verses explain that Allah gave human his sustenance consisting of plants and specifics. Vegetation and the specifics make food from the ground, water and sun. Allah make it easy for plants to make food. Vegetation is required by human and animals. In short, they are depend on one and another.
Think a moment, Are all the words from the Prophet Muhammad or from Allah ?, They are all miracle of Quran.
