It was a universal Divine Law, that when an apostle preached his people, and was rejected by them; God sent down upon the people various torments and hardship in order to admonish them and make them mindful. Usually when man finds himself free of wants, he will be puffed up with pride and vanity- excepted are those who believe in God and the Day of Doom. To this account the Egyptians under Pharaoh, who were mostly farmers and business men lived a life in affluence and welfare, having enslaved and exploited the Israelites unfairly. When they rejected Moses the Messenger of God, they were seized by drought and want of rain, so that their farm lands and even their trees were afflicted with dryness and death, and they were confronted with scarcity of grains and fruits, and all sorts of farm produces. They could have taken that for a warning and return back to God and their inner nature, but they didn't. On the contrary, they interpreted such afflictions by the tongue of their fancies, and superstitious tastes! Ignoring their own wickedness, they ascribed such events to Moses and his followers, as ill Omens. Had they considered their own evil deeds and oppressions, and transgressions, they would have found the root of those disasters in their own wickedness, for which God was putting them in troubles for warning: ``And We seized Pharaoh's people with drought and scarcity of fruits, perhaps they might be reminded.''
