Muhammad is the Messenger of Allah.

Muhammad is the Messenger of Allah.’ You will remain safe from misfortunes and if you like something do not mention it very often because mentioning it causes you great damage. If you need something from a person do not revile him behind his back because Allah drops it in his heart.’”
