13:11

Each person has been assigned guardian angels before him and behind him, who watch him by the command of Allah. The fact is that Allah never changes the condition of a people until they intend to change it themselves. If Allah wants to afflict a people with misfortune, none can ward it off, nor they can find any protector besides Him.
Meaning:-
Afflict: (of a problem or illness) cause pain or suffering to; affect or trouble
