Musnad Ahmad 1153:491

'Abd al-Samad narrated to us, he said: My father narrated to us, he said: Husayn narrated to us, and Yahya said: Muhammad ibn Ibrahim narrated to me, that Abu Salamah narrated to him, and there was a dispute between him and some people regarding land. He entered upon 'Aishah and mentioned that to her. She said: "O Abu Salamah, avoid the land, for the Messenger of Allah, peace and blessings of Allah be upon him, said: 'Whoever wrongs [another by taking] a span of land, it will be circled around his neck from seven earths.'"
