Simplify the following text for a Grade 8 native English-speaking person.
Original: It is forbidden for Somalis to fly the flag at half mast because it has the Shahada ( which says in Arabic There is no other God except Allah , Muhammad is the Messenger of Allah ) written on it so it will be an un-Islamic and disrespectful way to treat the flag .
Simplified: The Shahada says `` there is no other God except Allah , Muhammad is the Messenger of Allah '' .
