[Machine] I saw five companions of the Messenger of Allah ﷺ who used to trim their mustaches, leave their beards, and let their upper lip hair grow. They were Abu Umamah Al-Bahili, Al-Hajjaj bin 'Amir Al-Thumali, Al-Miqdam bin Ma'dikarib, Abdullah bin Busr Al-Mazini, and 'Utbah bin 'Abd Al-Salami. They used to trim along the edge of the lip.
رَأَيْتُ خَمْسَةً مِنْ أَصْحَابِ رَسُولِ اللهِ ﷺ يَقُمُّونَ شَوَارِبَهُمْ وَيُعْفُونَ لِحَاهُمْ وَيَصُرُّونَهَا أَبَا أُمَامَةَ الْبَاهِلِيَّ وَالْحَجَّاجَ بْنَ عَامِرٍ الثُّمَالِيَّ وَالْمِقْدَامَ بْنَ مَعْدِيكَرِبَ وَعَبْدَ اللهِ بْنَ بُسْرٍ الْمَازِنِيَّ وَعُتْبَةَ بْنَ عَبْدٍ السُّلَمِيَّ كَانُوا يَقُمُّونَ مَعَ طَرَفِ الشَّفَةِ
