Abu Bakrah (may Allah be pleased with him) narrates: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Oppression, rebellion, and severing ties of kinship are such sins that Allah punishes their perpetrator in this world, and in addition, reserves punishment for him in the Hereafter as well." Its chain is authentic. Narrated by al-Tirmidhi and Abu Dawood.
