Sayyiduna Sa'id bin Zayd (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: "Whoever seizes a span of land unjustly, a collar as heavy as seven earths will be placed around his neck (on the Day of Resurrection), and whoever is killed while protecting his wealth is a martyr."
Imam Humayd, may Allah have mercy on him, says: It was said to Sufyan: The narrator named Mu‘ammar has reported the addition of another person between Talhah and Sa‘id. So Sufyan said: I did not hear al-Zuhri mention anyone else between the two of them.
