Az-Zumar 39:21 الم تر ان الله انزل من السماء ماء فسلكه ينابيع في الارض ثم يخرج به زرعا مختلفا الوانه ثم يهيج فتراه مصفرا ثم يجعله حطاما ان في ذالك لذكرى لاولي الالباب ٢١

Do you not see that Allāh sends down rain from the sky and makes it flow as springs [and rivers] in the earth; then He produces thereby crops of varying colors; then they dry and you see them turned yellow; then He makes them [scattered] debris. Indeed in that is a reminder for those of understanding.
