وَعَنْ زَيْدِ بْنِ أَرْقَمَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنْ لَمْ يَأْخُذ شَارِبِهِ فَلَيْسَ مِنَّا» . رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيُّ وَالنَّسَائِيُّ

Zayd ibn Arqam reported that the Messenger of Allah ﷺ said, “Whoever does not trim his mustache is not one of us.” Ahmad, al-Tirmidhi, and al-Nasai transmitted it.
