What is the authenticity of the following hadiths: 1. "I will believe if they say Mount Uhud has moved, but I will not believe in an inner change in man"? 2. "Tell him to hold his father's private parts with his teeth" for one who prefers his people and lineage? 3. "I will pray for Paradise for women who wear trousers"?

Thank you for your inquiry about the narrations attributed to the Prophet, peace and blessings be upon him. Here is what we found regarding the hadiths you mentioned, in the order you presented them:

1. The hadith: "If you hear that a mountain has moved from its place, then believe it. But if you hear that a man has changed his character, do not believe it, for he will revert to what he was created upon." This was narrated by Imam Ahmad, but it is not authentic. There is a break in its chain of narration, and Al-Albani declared it weak. It is also contradicted by many authentic hadiths that encourage the improvement of character. 2. The hadith: "If anyone makes a boastful claim of the Jahiliyyah, then bite him on his father's penis, and do not use euphemisms." This was narrated by Ahmad, An-Nasa'i, and Ad-Diya', and it was authenticated by Al-Albani and others. We have discussed its meaning and the reason for such frankness in detailed fatwas previously. 3. The hadith: "O Allah, forgive the women of my Ummah who wear trousers. O people, wear trousers, for they are among your most concealing garments, and specifically, let your women wear them when they go out." This was narrated by Al-Uqaili, and Al-Albani stated that it is fabricated (mawdu').

In summary, the second hadith is authentic, while the others are weak.
