[Machine] The Messenger of Allah ﷺ mentioned the Magi and said, "They grow their beards long and shave their mustaches. So, oppose them." Ibn Umar used to trim his mustache in such a way that it was as short as a sheep's or a camel's cut.
ذَكَرَ رَسُولُ اللهِ ﷺ الْمَجُوسَ فَقَالَ إِنَّهُمْ يُوَفِّرُونَ سِبَالَهُمْ وَيَحْلِقُونَ لِحَاهُمْ فَخَالِفُوهُمْ قَالَ وَكَانَ ابْنُ عُمَرَ يَسْتَعْرِضُ سَبْلَتُهُ فَجَزَّهَا كَمَا تُجَزُّ الشَّاةُ أَوْ يُجَزُّ الْبَعِيرُ
