able to do so, then with his heart; and that is the weakest level of faith.”

Concerning Allah Most High’s words, “Those who go astray cannot harm you if you are rightly guided” [al-Mā’idah 105], being rightly guided includes fulfilling one’s duty to enjoin what is right and forbid what is wrong. This is why al-Siddīq said, “O people, you recite this verse but apply it where it does not belong. I heard the Messenger of Allah, may Allah bless him and grant him peace, say, ‘When people see wrongdoing and do not change it, Allah may soon afflict them all with a punishment from Him.’”
