I have seen this hadith many times: "From among my followers there will be some people who will consider illegal sexual intercourse, the wearing of silk, the drinking of alcoholic drinks and the use of musical instruments, as lawful …”.

I was listening to one scholar, who said that al-hirr in this hadith has been erroneously translated to “illegal sexual intercourse”. In fact, al-hirr means “woman’s private parts”. Is this true?

Yes, that is correct.
However, Imam talked about the illegal relationship in polite words.
