The Prophet (ﷺ) said: The angels do not come near three: the dead body of the unbeliever, one who smears himself with khaluq, and the one who is sexually defiled except that he performs ablution.
When the Prophet of Allah (ﷺ) conquered Makkah. The people of Makkah began to bring their boys and he would invoke a blessing on them and rub their heads. I was brought, but as I had been perfumed with khaluq, he did not touch me because of the khaluq.
A man came to the Messenger of Allah (ﷺ) and he had the mark of yellowness (of saffron). The Prophet (peace be upon him rarely mentioned a thing which he disliked before a man. When he went away, he said: Would that you tell this man that he should wash this off him.
I did not see any man with locks hanging down to shoulders in red robe more beautiful than the Messenger of Allah (ﷺ). Muhammad b. Sulaiman added: He had hair which touched his shoulders. Abu Dawud said: Isra'il also transmitted it in a similar way from Abu Ishaq saying: "(his hair) touched his shoulders". Shu'bah added: (His hair) reached the lobes of his ears.
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، أَخْبَرَنِي ابْنُ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ كَانَ أَهْلُ الْكِتَابِ - يَعْنِي - يَسْدِلُونَ أَشْعَارَهُمْ وَكَانَ الْمُشْرِكُونَ يَفْرُقُونَ رُءُوسَهُمْ وَكَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم تُعْجِبُهُ مُوَافَقَةُ أَهْلِ الْكِتَابِ فِيمَا لَمْ يُؤْمَرْ بِهِ فَسَدَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم نَاصِيَتَهُ ثُمَّ فَرَقَ بَعْدُ .
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.
