Surah Al-Mu'minun (The Believers), Verse 18

وَاَنْزَلْنَا مِنَ السَّمَآءِ مَآءً بِقَدَرٍ فَاَسْكَنّٰهُ فِی الْاَرْضِ وَاِنَّا عَلٰی ذَهَابٍ بِهٖ لَقٰدِرُوْنَ ۟

Wa anzalnaa minas samaaa'i maaa'am biqadarin fa-askannaahu fil ardi wa innaa 'alaa zahaabim bihee laqaa diroon

“And We send down water from the sky according to (due) measure, and We cause it to soak in the soil; and We certainly are able to drain it off (with ease).”
