Two things:
1) Kalbaani is wrong.
2) Kalbaani is not a proof. His words are not Wahi from Allaah. He is not a Nabi. He is a human. Every human besides the Ambiyaa gets certain things right and certain things wrong. They err. They make mistakes. This is one of his mistakes. What exactly about "Salafism" does he want to change? He doesn't want to change "Salafism". He wants to change Islaam. He wants to change the Qur'aan and the Ahaadeeth. For example, there is a Hadeeth which says homosexuals who commit sodomy are to be killed. He will want to remove this Hadeeth. Pretend it was never said. But no amount of pretense is going to make it "unsaid". He can pretend but the Kaafir world that he is trying to please will always know that it was said. That is the fact of the matter. Rasoolullaah صلى الله عليه وسلم said it. Neither he nor a galaxy of "scholars for dollars" can "un-say it". And you know what? People who do that shouldn't bother to call themselves Muslims. They may as well wear a cross and pray in a church. But if a person is trying to change Islaam, then he is not Muslim. You either accept Islaam as it is, or you don't accept it. The entire Deen of Islaam is based on Wahi from Allaah Ta`aalaa. Thus, it is Divine. The moment people start tampering in it, editing, adding and subtracting, it is no longer Islaam and is no longer Divine. The product of their tampering is man-made and cannot be referred to as "Islaam", because their tampering is not based on Wahi from Allaah.
Was-Salaam.
