It is narrated from Sayyiduna Abu Sa'id Khudri, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: Whoever among you sees an evil, let him change it with his hand; if he is not able to do so, then with his tongue; and if he is not able to do even that, then let him dislike it in his heart, and that is the weakest level of faith.

It is narrated from Sayyiduna Umar (may Allah be pleased with him), he said: O people! I heard the Noble Prophet (peace and blessings of Allah be upon him) saying: Whoever believes in Allah and the Last Day should never sit at a table where wine is being passed around; whoever believes in Allah and the Last Day should not enter the bathhouse without a lower garment; and any woman who believes in Allah and the Last Day should not enter the bathhouse at all.

Narrated by Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Whoever believes in Allah and the Last Day should not sit at a table where wine is being consumed.
