Arabic (Original)
حَدَّثَنَا إِسْحَاقُ بْنُ عِيسَى حَدَّثَنِي إِبْرَاهِيمُ يَعْنِي ابْنَ سَعْدٍ عَنِ الزُّهْرِيِّ وَيَعْقُوبُ حَدَّثَنِي أَبِي عَنِ ابْنِ شِهَابٍ عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ عَنِ ابْنِ عَبَّاسٍ قَالَ كَانَ الْمُشْرِكُونَ يَفْرُقُونَ رُءُوسَهُمْ وَكَانَ أَهْلُ الْكِتَابِ يَسْدِلُونَ قَالَ يَعْقُوبُ أَشْعَارَهُمْ وَكَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُحِبُّ وَيُعْجِبُهُ مُوَافَقَةُ أَهْلِ الْكِتَابِ قَالَ يَعْقُوبُ فِي بَعْضِ مَا لَمْ يُؤْمَرْ قَالَ إِسْحَاقُ فِيمَا لَمْ يُؤْمَرْ فِيهِ فَسَدَلَ نَاصِيَتَهُ ثُمَّ فَرَقَ بَعْدُ.
English Translation
The polytheists used to part their hair, while the People of the Book used to let their hair hang down. The Messenger of Allah (peace be upon him) liked to follow the People of the Book in matters where he had not been given specific commands. So he let his hair hang down. Then later he parted it.
