Sayyiduna Abu Umamah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Whoever swears a false oath in order to unlawfully seize the wealth of a Muslim, Allah makes Paradise forbidden for him and makes Hell necessary for him." It was asked: "O Messenger of Allah! Even if that wealth is very little?" He (peace and blessings be upon him) said: "Yes! Even if it is only a twig of arak (a small miswak stick)."
