Az-Zúmar 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
أَلَمۡ
تَرَ
أَنَّ
ٱللَّهَ
أَنزَلَ
مِنَ
ٱلسَّمَآءِ
مَآءٗ
فَسَلَكَهُۥ
يَنَٰبِيعَ
فِي
ٱلۡأَرۡضِ
ثُمَّ
يُخۡرِجُ
بِهِۦ
زَرۡعٗا
مُّخۡتَلِفًا
أَلۡوَٰنُهُۥ
ثُمَّ
يَهِيجُ
فَتَرَىٰهُ
مُصۡفَرّٗا
ثُمَّ
يَجۡعَلُهُۥ
حُطَٰمًاۚ
إِنَّ
فِي
ذَٰلِكَ
لَذِكۡرَىٰ
لِأُوْلِي
ٱلۡأَلۡبَٰبِ

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.

وَأَنزَلْنَا مِنَ السَّمَآءِ مَآءً طَهُوراً
(and We send down pure water from the sky) (25:48). So, Allah sends down water from the sky, and it settles in the earth, then He causes it to flow
