Chapter 90: Tricks
Narrated 'Amr bin Ash-Sharid: Abu Rafi 'sold a house to Sa 'd bin Malik for four-hundred Mithqal of gold, and said, "If I had not
heard the Prophet (ﷺ) saying, 'The neighbor has more right to be taken care of by his neighbor (than
anyone else),' then I would not have sold it to you."
