The World Federation One Stop Fiqh

Ruling 636

It is sufficient for one to perform one ghusl with the intention of several different recommended ghusls, except for those ghusls that have become recommended for one to perform on account of having done something, such as the ghusl for touching a corpse that has been given ghusl. To consider this type of ghusl as sufficing for several different recommended ghusls is problematic [i.e. based on obligatory precaution, one must not consider it as sufficing].
