Mukhtasar Bukhari

Sayyiduna Saeed bin Zaid (may Allah be pleased with him) says that I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "Whoever seizes even a little land of someone unjustly, on the Day of Resurrection, the seven layers of that land will be made into a collar and placed around the neck of that (oppressor)."

Narrated Ibn Umar (may Allah be pleased with them) that the Prophet (peace and blessings of Allah be upon him) said: "Whoever wrongfully takes a piece of land belonging to someone else, he will be made to sink down through the seven earths on the Day of Resurrection."
