And He it is Who sends the Winds as heralds of glad tidings, going before His Mercy, and We send down Pure water from the sky -
That with it, We may give Life to a dead land, and slake the thirst of things We have created - cattle and men in great numbers.[Qur'an 25:48-49]
Narrated Anas(RA): While the Prophet was delivering the Khutba on a Friday, a man stood up and said, "O, Allah's Apostle! The livestock and the sheep are dying, so pray to Allah for rain." So he (the Prophet(PBUH)) raised both his hands and invoked Allah (for it).
