The Prophet (ﷺ) said, "When Allah intends to show mercy to a people, He collects their Prophet before them and makes him a herald to happiness for them in the Hereafter; and when He intends to destroy a people, He punishes them while their Prophet is alive, and destroys them while he is alive and watches them and makes him witness their destruction because they disbelieved in him and disobeyed his commands".
