The Prophet ﷺ said: He who copies any people is one of them.  

أبو داود:٤٠٣١ – حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا أَبُو النَّضْرِ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ ثَابِتٍ حَدَّثَنَا حَسَّانُ بْنُ عَطِيَّةَ عَنْ أَبِي مُنِيبٍ الْجُرَشِيِّ عَنِ ابْنِ عُمَرَ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ تَشَبَّهَ بِقَوْمٍ فَهُوَ مِنْهُمْ
