question #2 Sahih al-Bukhari 6981, Book 90, Hadith 28 : How does the concept of neighborly rights influence property transactions in Islamic teachings?

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.”
