Is it obligatory for one who sees what is wrong to forbid it?

The questioner : May Allah reward you, O honorable Shaykh. Is it obligatory for everyone who sees what is wrong to forbid it?

The Shaykh : Yes, it is obligatory for everyone who sees what is wrong to forbid it, based on the saying of the Prophet (peace and blessings be upon him): But how should one forbid it? That is the important point. Does one forbid it with violence, shouting at this man and cursing him? Or does one conceal it and forbid it in the best manner? That is the important point, and this is what many of the brothers who enjoin good and forbid evil miss. You find them using violence, and perhaps in his heart he wants to avenge himself, for example. And this is a mistake. The obligatory thing when forbidding evil is that you intend by it the reform of your brother. And if you intend this, then take the easiest path to reform him. Yes.
