Abu Rafiʿ sold a house to Saʿd 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."
سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ الْجَارُ أَحَقُّ بِصَقَبِهِ مَا أَعْطَيْتُكَ
