It was narrated from Abu Umamah that : The Messenger of Allah (ﷺ) said: "Whoever seizes the wealth of a Muslim unlawfully by means of his (false) oath, Allah makes the Fire required for him, Paradise unlawful for him." A man said to him: "O Messenger of Allah, even if it is something small?" He said: "Even if it is a twig of an Arak tree."
