hakim:4008ʿAlī b. ʿĪsá al-Ḥīrī > Musaddad b. Qaṭan > ʿUthmān b. Abū Shaybah > Wakīʿ > Ibn Abū Labībah / Muḥammad b. ʿAbd al-Raḥman from his father > Ibn Masʿūd

that he mentioned the statement of Allah ﷻ "We sent Nūḥ to his nation... (Nūḥ 71:1)" then mentioned that Nūḥ took a bath and saw his son looking at him. He then said, "You're looking at me while I'm taking a bath? May Allah discolor you." ˹Ibn Masʿūd˺ said: he was then darkened and he is the father of Sūdān (the African race).  

This ḥadīth has a ṣaḥīḥ chain but they (Bukhārī and Muslim) did not collect it. Dhahabī said that scholars consider Muḥammad b. Abū Labībah as weak.
الحاكم:٤٠٠٨حَدَّثَنِي عَلِيُّ بْنُ عِيسَى الْحِيرِيُّ ثنا مُسَدَّدُ بْنُ قَطَنٍ ثنا عُثْمَانُ بْنُ أَبِي شَيْبَةَ ثنا وَكِيعٌ عَنِ ابْنِ أَبِي لَبِيبَةَ وَهُوَ مُحَمَّدُ بْنُ عَبْدِ الرَّحْمَنِ عَنْ جَدِّهِ عَنِ ابْنِ مَسْعُودٍ

أَنَّهُ ذَكَرَ قَوْلَ اللَّهِ ﷻ {إِنَّا أَرْسَلْنَا نُوحًا إِلَى قَوْمِهِ} [نوح 1] فَذَكَرَ أَنَّ نُوحًا اغْتَسَلَ فَرَأَى ابْنَهُ يَنْظُرُ إِلَيْهِ فَقَالَ: تَنْظُرُ إِلَيَّ وَأَنَا أَغْتَسِلُ؟ خَارَ اللَّهُ لَوْنَكَ! قَالَ: فَاسْوَدَّ فَهُوَ أَبُو السُّودَانِ۔
