Is there a Hadith concerning the deceased who asks his relatives to remind him of what should be said when questioned in the grave?

Teaching the deceased is not obligatory by consensus, nor was it a common practice among Muslims during the time of the Prophet and his successors. Rather, it is reported from a number of companions. The opinions of the imams regarding it have varied between recommendation, disapproval, and permissibility, with the latter being the most equitable of opinions.
