question #2 Sahih al-Bukhari 3944, Book 63, Hadith 168 : What was the Prophet Muhammad’s (ﷺ) approach to following the customs of the People of the Scriptures when there was no specific instruction?

The Prophet (ﷺ) used to keep his hair falling loose while the pagans used to part their hair, and the People
of the Scriptures used to keep their hair falling loose, and the Prophet (ﷺ) liked to follow the People of the
Scriptures in matters about which he had not been instructed differently, but later on the Prophet (ﷺ)
started parting his hair.
