Zakaat - A cause of Windstorm, Earthquake etc.

Ali and Aboo Hurayrah radhiyallahu anhumaa reports that Rasoolullah Sallallahu alayhi wasallam  said, "When people of my Ummah do fifteen things" ... "When Zakaat is looked upon as a penalty (i.e., people will pay Zakaat with a heavy heart, as though it is a penalty), then look for violent windstorms, earthquakes, men being swallowed by the earth, metamorphosis, stones being pelted from the skies, and calamities following one another in rapid succession, like beads of rosary falling one after the other when its string is cut."
