(Al-Hajj) 22 : 63
أَلَمْ تَرَ أَنَّ اللَّهَ أَنْزَلَ مِنَ السَّمَاءِ مَاءً فَتُصْبِحُ الْأَرْضُ مُخْضَرَّةً ۗ إِنَّ اللَّهَ لَطِيفٌ خَبِيرٌ
Didn’t you see that Lord Allah has sent down water from the sky and the earth becomes green? Indeed, Allah is the Knower of innermost and acquainted.
See explanation 6: 103; 13: 4 and 18: 45.
