6:99
It is He Who sendeth down rain from the skies: with it We produce vegetation of all kinds: from some We produce green (crops), out of which We produce grain, heaped up (at harvest); out of the date-palm and its sheaths (or spathes) (come) clusters of dates hanging low and near: and (then there are) gardens of grapes, and olives, and pomegranates, each similar (in kind) yet different (in variety): when they begin to bear fruit, feast your eyes with the fruit and the ripeness thereof. Behold! in these things there are signs for people who believe.
Chlorophyll
‘Chlorophyll’ is the only ‘factory’ on Earth that produces food: it is the green pigment that converts energy from the sun’s energy, carbon dioxide and water to produce food for man and animals and this is referred to as ‘chlorophyll a’. ‘Chlorophyll b’ has a different molecular structure and converts light energy from the sun, followed by a complex chemical reaction that produces sugar and then starch. Therefore, the basis of the formation of seeds and fruits is this green ‘factory’.
“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….” Qur’ān 6: 99
Scholars of Qur’ānic exegesis said ‘khadran’ means something green. Qurtubi, a classic scholar of Qur’ānic commentary, explained the verse, “We brought forth from the plants something green” and Ibn al-Jawzi further explains, “We bring forth from it, that is – from the green thing – clustered grains like wheat and barley .” So from this ‘green substance’ are the fruits and seeds produced.
