Sayyiduna Abu Huraira (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "Avoid obscene speech, for Allah Almighty does not like the one who is obscene and foul-mouthed. And avoid oppression, for oppression will appear as darknesses on the Day of Resurrection. And avoid miserliness, for miserliness invited those before you, so they shed each other's blood and violated the rights of kinship because of it."
