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
مسند امام احمد بن حنبل · Hadith 2209
It was narrated that Ibn Abbas (RA) said: The mushrikeen used to part their hair in the middle and the People of the Book used to let their hair fall over their foreheads, and the Messenger of Allah (PBUH) liked to do the same as the People of the Book - Ya'qoob said: in some matters concerning which he had received no command; Ishaq said: in that concerning which he had received no command - so he let his hair fall over his forehead, then later on he parted it.
