Is it possible for the deceased to maintain a connection with their grieving family after death? Can they see or hear their circumstances or witness their family's daily lives? Please share references from the Quran and sayings of the Imams.
According to narrations, deceased soul can come to his house and family once a year, or once a month or weekly, depending on his degree. If he sees his family doing good deeds, he will be happy and if he sees them in bad situation, he will be sad. (Biharul Anwar V.6, page 257).
Wassalam.
