[Machine] Malik ibn Anas mentioned that some people pluck their mustaches, so he said that those who do so should be reprimanded, as there is no tradition of the Prophet ﷺ regarding plucking the mustache. Rather, it displays the shape of the lips and mouth. Malik ibn Anas said that shaving the mustache is an innovation that has appeared among the people.
ذَكَرَ مَالِكُ بْنُ أَنَسَ إِحْفَاءَ بَعْضِ النَّاسِ شَوَارِبَهُمْ فَقَالَ مَالِكٌ يَنْبَغِي أَنْ يُضْرَبَ مَنْ صَنَعَ ذَلِكَ فَلَيْسَ حَدِيثُ النَّبِيِّ ﷺ فِي الْإِحْفَاءِ وَلَكِنْ يُبْدِي حَرْفَ الشَّفَتَيْنِ وَالْفَمَ قَالَ مَالِكُ بْنُ أَنَسٍ حَلْقُ الشَّارِبِ بِدْعَةٌ ظَهَرَتْ فِي النَّاسِ
