It is narrated from Sayyiduna Thawban (may Allah be pleased with him), he says: If two people sever relations with each other for more than three days, and then one of them dies (or in the case that) both die while they are still boycotting each other, then both are ruined, meaning they become deserving of punishment and Hell. And any person who oppresses his neighbor to the extent that the neighbor, being distressed by this oppression, is forced to leave his home, then that person is certainly ruined as well.
