Reasons & Benefits Of Rain

It is He who sends down rain from the sky from it ye drink, and out of it (grows) 
the vegetation on which ye feed your cattle. 
With it He produces for you corn, olives, date-palms, grapes and every kind of 
fruit verily in this is a sign for those who give thought. 
(Surah An-Nahal) {Verse No 10,11}
