Does Al-Bukhari 3508 hadith contradicts the Qur'an Honourable?

Sahih Al-Bukhari 3508: The Prophet (ﷺ) said, "If somebody claims to be the son of any other than his real father knowingly, he but disbelieves in Allah, and if somebody claims to belong to some folk to whom he does not belong, let such a person take his place in the (Hell) Fire." I find the second part problematic: *"and if somebody claims to belong to some folk to whom he does not belong, let such a person take his place in the (Hell) Fire."* In the Qur'an Kerim, it states clearly: **"Indeed, We have dignified the children of Adam, carried them on land and sea, granted them good and lawful provisions, and privileged them far above many of Our creatures."** Qur'an Kerim 17:70 Further a hadith confirms this: *“Verily, **Allah has removed from you the pride of the time of ignorance, with its boasting of ancestors,** for one can only be a righteous believer or a miserable evildoer. All of the people are the children of Adam, and Adam was created from dust.”* - Source: Sunan al-Tirmidhī 3955 (Grade: Sahih (authentic) according to Al-Albani.) According to this Qur'an Kerim Ayah and the Al-Tirmidhi hadith: You, me, all of us are Children of The Prophet Adam SAWS or 'Children of Adam' which means: I can clearly claim to be of any ethnicity: Arab, Chinese, Kurdish, Turkish, European, Malawi etc. because **we are all One Tribe.** And who knows except Allah SWT who was yours or mine ancestor millennia ago. Also, there is a reason that all of us, Muslims and all others are called Brothers and Sisters in Humanity for a reason. Most probably our ethnicities changed through ancestry and time. So, *"and if somebody claims to belong to some folk to whom he does not belong, let such a person take his place in the (Hell) Fire."* This part of that first hadith seems problematic since it clearly contradicts Qur'an Honourable in this aspect. And rejecting Qur'an Kerim is also an Act of Kufr. Since I'm kind of puzzled with this, could you resolve this question for me. Thanks and Selam,
