Hadith 5164
Sayyiduna Ya'la bin Murrah (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings of Allah be upon him) say: "Whoever seizes a span of land unjustly, Allah will make him dig it until he reaches the seven earths, then on the Day of Resurrection a collar will be placed around his neck which will remain until judgment is passed among the people."
