It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him), he said: The Messenger of Allah (peace and blessings be upon him) said: "Beware of miserliness, for indeed it destroyed those before you. They shed each other's blood and severed their ties of kinship, and oppression will be many darknesses on the Day of Resurrection. And beware of foul speech. Indeed, Allah does not like the one who is obscene in speech and deliberately abusive."
