What did the Prophet Muhammad (saw) say about taking land unjustly?
 Narrated Abu Salama:                     That there was a dispute between him and some people (about a piece of land). When he told `Aisha about it, she said, "O Abu Salama! Avoid taking the land unjustly, for the Prophet said, 'Whoever usurps even one span of the land of somebody, his neck will be encircled with it down the seven earths."
