But those who wronged changed [those words] to a statement other than that which had been said to them, so We sent down upon those who wronged a punishment [i.e., plague] from the sky because they were defiantly disobeying.
The wrongdoers among them changed what they were told to do and say, and entered dragging themselves on their rears, saying, ‘A grain in a hair’, mocking Allah’s sacred law. Due to their actions He sent down a torment from the sky upon the wrongdoers among them, because they trespassed over the limits of the law and disobeyed His command.
