Hadith 1425
It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever usurps the right of his Muslim brother by swearing a false oath, Allah will make Paradise forbidden for him and will make Hell necessary for him." The Companions said: O Messenger of Allah (peace and blessings be upon him)! Even if that right is small? He (peace and blessings be upon him) said: "Even if it is a twig of the arak tree, even if it is a twig of the arak tree, even if it is a twig of the arak tree." He said it three times.
