Ruling on holding classes to teach people how to wash the dead

What is the ruling on holding classes to teach people how to wash the dead?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

Teaching people how to wash the dead is good and is acceptable according to sharee’ah. There is nothing wrong with that, because some people do not know how to wash the dead properly, so there is a real need to know how to wash the dead.
