What is the difference between additional innovation (bid'ah) and original innovation (bid'ah)?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: What is the difference between additional innovation (bid'ah) and original innovation (bid'ah)?

Answer:
Original innovation (bid'ah) is that which has no basis in the Shari'ah at all, such as instituting a fifth or sixth prayer alongside the obligatory prayers. He says, "I am adding good to the obligatory prayers; I am adding one more. Adding good is an original innovation (bid'ah) with no basis. As for additional innovation (bid'ah), it is when an act has a basis, but one adds to it, subtracts from it, or adds something to it. This is additional innovation (bid'ah). Yes.
