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.  

مَا رَأَيْتُ مِنْ ذِي لِمَّةٍ أَحْسَنَ فِي حُلَّةٍ حَمْرَاءَ مِنْ رَسُولِ اللَّهِ ﷺ زَادَ مُحَمَّدُ بْنُ سُلَيْمَانَ لَهُ شَعْرٌ يَضْرِبُ مَنْكِبَيْهِ  

The Messenger of Allah ﷺ had hair which reached the lobes of his ears.  

كَانَ رَسُولُ اللَّهِ ﷺ لَهُ شَعْرٌ يَبْلُغُ شَحْمَةَ أُذُنَيْهِ  

The hair of the Messenger of Allah ﷺ were up to the lobes of his ears.  

كَانَ شَعْرُ رَسُولِ اللَّهِ ﷺ إِلَى شَحْمَةِ أُذُنَيْهِ  

The hair of Messenger of Allah ﷺ were halfway down his ears.  

كَانَ شَعْرُ رَسُولِ اللَّهِ ﷺ إِلَى أَنْصَافِ أُذُنَيْهِ  

The hair of the Messenger of Allah ﷺ were above wafrah and below jummah.  

كَانَ شَعْرُ رَسُولِ اللَّهِ ﷺ فَوْقَ الْوَفْرَةِ وَدُونَ الْجُمَّةِ
