What is the ruling on filming the washing of the deceased and offering it for sale under the pretext of reminding people of death?

Photographing the deceased during washing is not permissible, due to the prohibition of the Prophet (peace and blessings be upon him) against photographing living beings and his curse upon photographers. As for explaining the method of washing the deceased in an audio recording (cassette) that is distributed and sold, there is no harm in it, just like teaching people how to pray and other similar matters, provided that it does not include any photography.
