Narrated Râfi' the freed slave of the Prophet (ﷺ) that he went to Sa'd bin Abi Waqqâs and asked him to buy from him the (two) dwellings which were in his house. Sa'd said, "By Allâh, I will not pay more than four thousand (Dirhams) by instalments." Râfi ' said, "I have been offered five hundred Dinârs (for it) and had I not heard the Prophet (ﷺ) saying, 'The neighbour has more right than anyone else because of his nearness ', I would not give them to you for four thousand (Dirhams) while I am offered five hundred Dinârs (one Dinâr equals ten Dirhams) for them." So, he sold it to Sa'd. [3:459-O.B]
