نص قرآني / حديث شريفSilat ar-rahim, keeping ties with relatives, is a major duty. The Prophet ﷺ said: "Whoever wishes to have his provision expanded and his life extended, let him keep ties with his relatives" (Bukhari 5985, Muslim 2557) and "The one who cuts family ties will not enter Paradise" (Bukhari 5984, Muslim 2556). Keeping ties means visiting, calling, helping and forgiving, even when the other side does not do the same (Bukhari 5991).
نص قرآني / حديث شريفThe neighbour also has rights: Jibril kept recommending good treatment of the neighbour until the Prophet ﷺ thought he would be made an heir (Bukhari 6014, Muslim 2624).
نص قرآني / حديث شريفElderly relatives deserve respect and care: the Prophet ﷺ said that honouring the elderly is part of honouring Allah (Abu Dawud 4843). Care for them at home or arrange good care, and include them in family life.
