One of the cities of Syria was infected with pestilence, and the plague killed the citizens one after another. Meanwhile, a large group of people escaped the cities in thousands leaving their homes. with the hope of being saved from that dreadful disaster. They reached a green valley with a nice climate, and were saved; but as the verse alludes: ``Allah said to them: `Die you all!' And all of them passed away at once!'' This was because, instead of being thankful to God for saving their life and leading them to a bountiful and safe place, they were puffed up with pride and vanity, and thought that it was their prudence and plan that saved them so! They had to be grateful, but gave no thanks and therefore by God's order they died with the same plague that they escaped it for fear of death.
