Musnad Ahmad 1153:2124

'Abd al-Samad narrated to us, Harb narrated to us, he said: Yahya narrated to me, from Muhammad ibn Ibrahim, that Abu Salamah narrated to him—and there was a dispute between him and some people regarding land—that 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, he will be encircled by it from seven earths.'"
