Ash-Shuraa 42:28

Wahuwa allathee yunazzilu alghaythamin baAAdi ma qanatoo wayanshuru rahmatahuwahuwa alwaliyyu alhameed

And it is He who sends down the rain after they had despaired and spreads His mercy. And He is the Protector, the Praiseworthy.

And He is the One who sends down rain after they have lost hope, and He extends His mercy. And He is the Guardian, Worthy of all praise.
