Messenger of Allah ﷺ 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 Messenger of Allah ﷺ liked to follow the people of the Scriptures in the matters about which he was not instructed otherwise. Then Messenger of Allah ﷺ parted his hair.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَسْدِلُ شَعَرَهُ وَكَانَ الْمُشْرِكُونَ يَفْرُقُونَ رُءُوسَهُمْ فَكَانَ أَهْلُ الْكِتَابِ يَسْدِلُونَ رُءُوسَهُمْ وَكَانَ رَسُولُ اللَّهِ ﷺ يُحِبُّ مُوَافَقَةَ أَهْلِ الْكِتَابِ فِيمَا لَمْ يُؤْمَرْ فِيهِ بِشَىْءٍ ثُمَّ فَرَقَ رَسُولُ اللَّهِ ﷺ رَأْسَهُ  

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.  

أَنَّ النَّبِيَّ ﷺ كَانَ يَسْدِلُ شَعْرَهُ وَكَانَ الْمُشْرِكُونَ يَفْرُقُونَ رُءُوسَهُمْ وَكَانَ أَهْلُ الْكِتَابِ يَسْدِلُونَ رُءُوسَهُمْ وَكَانَ النَّبِيُّ ﷺ يُحِبُّ مُوَافَقَةَ أَهْلِ الْكِتَابِ فِيمَا لَمْ يُؤْمَرْ فِيهِ بِشَىْءٍ ثُمَّ فَرَقَ النَّبِيُّ ﷺ رَأْسَهُ  

The Prophet ﷺ used to copy the people of the Scriptures in matters in which there was no order from Allah. The people of the Scripture used to let their hair hang down while the pagans used to part their hair. So the Prophet ﷺ let his hair hang down first, but later on he parted it.  

كَانَ النَّبِيُّ ﷺ يُحِبُّ مُوَافَقَةَ أَهْلِ الْكِتَابِ فِيمَا لَمْ يُؤْمَرْ فِيهِ وَكَانَ أَهْلُ الْكِتَابِ يَسْدِلُونَ أَشْعَارَهُمْ وَكَانَ الْمُشْرِكُونَ يَفْرُقُونَ رُءُوسَهُمْ فَسَدَلَ النَّبِيُّ ﷺ نَاصِيَتَهُ ثُمَّ فَرَقَ بَعْدُ  

Ibn Abbas reported that the People of the Book used to let their hair fall (on their foreheads) and the polytheists used to part them on their heads, and Messenger of Allah ﷺ liked to conform his behaviour to the People of the Book in matters in which he received no command (from God) ; so Messenger of Allah ﷺ let fall his hair upon his forehead, and then he began to part it after this.  

كَانَ أَهْلُ الْكِتَابِ يَسْدُلُونَ أَشْعَارَهُمْ وَكَانَ الْمُشْرِكُونَ يَفْرُقُونَ رُءُوسَهُمْ وَكَانَ رَسُولُ اللَّهِ ﷺ يُحِبُّ مُوَافَقَةَ أَهْلِ الْكِتَابِ فِيمَا لَمْ يُؤْمَرْ بِهِ فَسَدَلَ رَسُولُ اللَّهِ ﷺ نَاصِيَتَهُ ثُمَّ فَرَقَ بَعْدُ  

The Messenger of Allah [SAW] used to let his hair hang down (without a parting) and the Mushrikun used to part their hair. The Messenger of Allah [SAW] liked to act in accordance with the People of the Book, in matters where no specific command had been given to him. Then the Messenger of Allah [SAW] parted his hair after that.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَسْدُلُ شَعْرَهُ وَكَانَ الْمُشْرِكُونَ يَفْرُقُونَ شُعُورَهُمْ وَكَانَ رَسُولُ اللَّهِ ﷺ يُحِبُّ مُوَافَقَةَ أَهْلِ الْكِتَابِ فِيمَا لَمْ يُؤْمَرْ فِيهِ بِشَىْءٍ ثُمَّ فَرَقَ رَسُولُ اللَّهِ ﷺ بَعْدَ ذَلِكَ  

The people of the Book used to let their hair hand down, and the polytheists used to part their hair. The Messenger of Allah ﷺ like to confirm with the People of the Book in the matters about which he had received no command. Hence he Messenger of Allah ﷺ let his forelock hang down but afterwards he parted it.  

كَانَ أَهْلُ الْكِتَابِ يَعْنِي يَسْدِلُونَ أَشْعَارَهُمْ وَكَانَ الْمُشْرِكُونَ يَفْرُقُونَ رُءُوسَهُمْ وَكَانَ رَسُولُ اللَّهِ ﷺ تُعْجِبُهُ مُوَافَقَةُ أَهْلِ الْكِتَابِ فِيمَا لَمْ يُؤْمَرْ بِهِ فَسَدَلَ رَسُولُ اللَّهِ ﷺ نَاصِيَتَهُ ثُمَّ فَرَقَ بَعْدُ
