[Ali Imran]

So you will take anything from external sources as long as they are compatible to your faith?

The Quran does not teach moslems to believe books from the tanahk..  This is Bidah...and you do not follow the teachings of Muhammad...

No need to thanks mẹ for educating you how to be a moslem

There is no serious bida'ah if we take Isaiah as a prophet, even though his name wasn't mentioned explicitly in the Quran. The Messenger of Allah صلي الله عليه وسلم says that there are as many as 125,000 prophets sent, with many of them sent to the children of Israel.

So, I can say Isaiah was a prophet, with a disclaimer which I've often made, wallahu 'alam.

So no, you're not educating me. I am already educated on that.
