حَدَّثَنَا عَلِيُّ بْنُ إِسْحَاقَ قَالَ أَخْبَرَنَا عَبْدُ اللَّهِ وَعَتَّابٌ قَالَ حَدَّثَنَا عَبْدُ اللَّهِ قَالَ أَخْبَرَنَا يُونُسُ عَنِ الزُّهْرِيِّ قَالَ حَدَّثَنِي عُبَيْدُ اللَّهِ عَنْ ابْنِ عَبَّاسٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَسْدِلُ شَعْرَهُ وَكَانَ الْمُشْرِكُونَ يَفْرُقُونَ رُءُوسَهُمْ وَكَانَ أَهْلُ الْكِتَابِ يَسْدِلُونَ شُعُورَهُمْ وَكَانَ يُحِبُّ مُوَافَقَةَ أَهْلِ الْكِتَابِ فِيمَا لَمْ يُؤْمَرْ فِيهِ بِشَيْءٍ ثُمَّ فَرَقَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَأْسَهُ
مسند امام احمد بن حنبل · Hadith 2605
It was narrated from Ibn 'Abbas (RA) that the Messenger of Allah (PBUH) used to let his hair hang down. The mushrikecti used to part their hair and the people of the Book used to let their hair hang down, and he liked to do the same as the people of the Book in matters concerning which he had received no command. Then the Messenger of Allah (PBUH)parted his hair.
