Is it permissible for someone who commits some sins to forbid people from evil, and does this fall under the Almighty’s saying: "Do you enjoin righteousness upon the people and forget yourselves?"

"It is incumbent upon the one who enjoins good and forbids evil to practice what he preaches and to abstain from what he forbids, for this is more impactful on people's hearts. However, it is not a condition for him to be just, as that would close the door to enjoining good and forbidding evil. Indeed, a person is obligated to do two things: avoid evil and forbid it, and neither obligation is abrogated by neglecting the other. The sacred texts that condemn those who enjoin righteousness while forgetting themselves condemn their failure to act upon what they enjoin, not their act of enjoining good. The intent is not to condemn them for enjoining good, but for neglecting to act upon it. Thus, enjoining good and forbidding evil are two obligations, neither of which is abrogated by neglecting the other, and a person who is a transgressor is not exempted from enjoining good and forbidding evil on account of his transgression."
