Rulings Of Returning After The Funeral Salah

Whoever accompanied the funeral should not return home without offering the funeral Ṣalāĥ; after the Ṣalāĥ, he may return, seeking permission from the family-members of the deceased person. There is no need to ask permission for returning after the burial.
