Is the explanation correct which states that Thaniyyat al-Wada' (the Farewell Mountain Pass) was a den of corruption, and that the Prophet, peace and blessings be upon him, traversed it by Allah's command to prove the Jews' falsehood, and that women received him there?

Thaniyat al-Wada' is a place near Medina, named as such because travelers used to bid farewell there. Scholars have differed on its location, whether it was to the north or south of Medina. It was used for various occasions, such as horse racing. As for what some people transmit, that it was a den of corruption or a place of perdition in the pre-Islamic era (Jahiliyyah), no such information has been reported in the books of Sunnah (definition), history, or biographies.
