Have you not considered those who left their homes in many thousands, fearing death? Allāh said to them, "Die"; then He restored them to life. And Allāh is the possessor of bounty for the people, but most of the people do not show gratitude.
Do you not know, O Prophet, about those who left their homes in huge numbers fearing death due to the plague or something similar? This refers to a group of people from the Israelites. Allah said to them, ‘Die!’ and they did. Then Allah brought them back to life to show them that everything is in His Hands and that they have no control over any benefit or harm. Allah is Gracious and Bountiful to people, but most people are ungrateful for His favours.
