What is the ruling on one who speaks about what they witnessed in the deceased during ghusl, and is their action forbidden, and what must they do?

Washing the deceased, shrouding them, burying them, and concealing any sightings that might lead to ill-conceptions or wound the feelings of their relatives, carries immense reward, for the Prophet, peace and blessings be upon him, said: "Whoever washes a deceased person and conceals what they see will be forgiven forty times. And whoever shrouds a deceased person, Allah will clothe them with the finest silk and brocade of Paradise. And whoever digs a grave for a deceased person and inters them in it, will be rewarded as if they housed someone until the Day of Resurrection." The sanctity of the deceased remains after their death, and whoever speaks ill of them must seek Allah's forgiveness and repent to Him.
