It is narrated from Abu Salamah that there was a dispute between him and some people over land. He went to Sayyidah Aishah (may Allah be pleased with her) and told her about it. Sayyidah Aishah (may Allah be pleased with her) said: O Abu Salamah, keep away from disputes over land, for I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever commits wrong in a matter of as much as a span of land will be made to wear a collar of seven earths on the Day of Resurrection."
