Abdulhussain al-Mosawi wrote in his book (letter 12):
There is no room to wonder any longer, then, especially when we discern the fact that their authority has been sanctioned by Allah unto people through His prophets, providing proofs and arguments for it, as indicated by the explanation of His saying: “And ask the Messengers whom We sent before thee (Qur’an, 43:45)
And here he was talking about authority of ahlalbayt. And by Allah, abdulhussain lied upon Quran!
Because Allah said:
[Shakir 43:45] And ask those of Our messengers whom We sent before you: Did We ever appoint gods to be worshipped besides the Beneficent Allah?
Abdulhussain simply quoted first part of verse, and claimed that it’s about authority of ahlalbayt.
