Abu Sufyan bin Jabir bin Atik narrates from his father that he heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever usurps the wealth of a Muslim by his (false) oath, Allah makes Paradise forbidden for him and makes the Fire obligatory for him." It was said: O Messenger of Allah, even if it is something small? He said: "Even if it is only a miswak."
