Narrated Ibn ‘Abbas:
Allah’s Apostle used to let his hair hang down while the infidels used to part their hair. The people
of the Scriptures were used to letting their hair hang down and Allah’s Apostle liked to follow the
people of the Scriptures in the matters about which he was not instructed otherwise. Then Allah’s
Apostle parted his hair.
