وَهُوَ ٱلَّذِى يُرْسِلُ ٱلرِّيَٰحَ بُشْرًۢا بَيْنَ يَدَىْ رَحْمَتِهِۦ ۖ حَتَّىٰٓ إِذَآ أَقَلَّتْ سَحَابًۭا ثِقَالًۭا سُقْنَٰهُ لِبَلَدٍۢ مَّيِّتٍۢ فَأَنزَلْنَا بِهِ ٱلْمَآءَ فَأَخْرَجْنَا بِهِۦ مِن كُلِّ ٱلثَّمَرَٰتِ ۚ كَذَٰلِكَ نُخْرِجُ ٱلْمَوْتَىٰ لَعَلَّكُمْ تَذَكَّرُونَ
And He it is Who sendeth the winds as tidings heralding His mercy, till, when they bear a cloud heavy (with rain), We lead it to a dead land, and then cause water to descend thereon and thereby bring forth fruits of every kind. Thus bring We forth the dead. Haply ye may remember.
Surah Al-A'raaf(7:57)
