It is narrated from Sayyiduna Saeed bin Zaid (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever seizes even a handspan of land unjustly, on the Day of Resurrection it will be made into a collar from the seven earths and placed around his neck."
