Hasan (may Allah have mercy on him) said: One of the companions of the Messenger of Allah (peace and blessings be upon him) recited this verse: "O you who have believed, take care of your own selves. He who has gone astray will not harm you when you have been guided" (__QUR_N__). So someone said: Leave the mention of this, it is not for you. When enjoining good and forbidding evil is accepted from you, then it is for you.
