Sayyiduna Ya'la bin Murrah (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) saying: "Whoever unjustly takes a hand-span of land or more will be made to carry it about on the Day of Resurrection until he reaches the water (beneath), then carry it to the gathering place (al-Mahshar)."
