Grains are mentioned in the Quran in these verses:
[2:261] The example of those who spend their monies in the cause of God is that of a grain that produces seven spikes, with a hundred grains in each spike. God multiplies this manifold for whomever He wills. God is Bounteous, Knower.
[6:95] God is the One who causes the grains and the seeds to crack and germinate. He produces the living from the dead, and the dead from the living. Such is God; how could you deviate!
[6:99] He is the One who sends down from the sky water, whereby we produce all kinds of plants. We produce from the green material multitudes of complex grains, palm trees with hanging clusters, and gardens of grapes, olives and pomegranate; fruits that are similar, yet dissimilar. Note their fruits as they grow and ripen. These are signs for people who believe.
[12:47] He said, “What you cultivate during the next seven years, when the time of harvest comes, leave the grains in their spikes, except for what you eat.
[36:33] One sign for them is the dead land: we revive it and produce from it grains for their food.
[50:9] And we sent from the sky blessed water, to grow with it gardens and grains to be harvested.
[55:12] Also grains and the spices.
[78:15] To produce with it grains and plants.
[80:27] We grow in it grains.
