Qur'an, Al-An'am, Surah 6:100
It is He who sends down water from the sky, with which sprout buds of every kind. From these He brings forth the green vegetation, the thick variegated grain, and the clusters of dates that stem from the palm trees, vineyards, and the groves of olives and pomegranates, which are all so alike yet so different. Behold their fruits when they reach perfection. Indeed in all these are signs for those who believe.
