The Prophet ﷺ said, "He who slaps the cheeks, tears the clothes and follows the tradition of the Days of Ignorance is not from us." (Using translation from Bukhārī 1297)  

عَنِ النَّبِيِّ ﷺ قَالَ «لَيْسَ مِنَّا مَنْ ضَرَبَ الْخُدُودَ وَشَقَّ الْجُيُوبَ وَدَعَا بِدَعْوَى الْجَاهِلِيَّةِ»  

[Machine] The Messenger of Allah ﷺ said, "So I asked her, and she said, 'He said, 'He is not one of us who shaves, plucks, or tattoos.'''  

قَالَ رَسُولُ اللهِ ﷺ فَسَأَلْتُهَا فَقَالَتْ قَالَ «لَيْسَ مِنَّا مَنْ سَلَقَ وَحَلَقَ وَخَرَقَ»  

[Machine] The Messenger of Allah ﷺ said, "He is not one of us who shaves his head, plucks his eyebrows, or makes incisions in his skin."  

قَالَ رَسُولُ اللهِ ﷺ «لَيْسَ مِنَّا مَنْ حَلَقَ وَسَلَقَ وَخَرَقَ»  

"When Abu Musa was close to death, his wife screamed and he said: 'Do you not know what the Messenger of Allah said?" She said: 'Yes, Then she fell silent and it was said to her after that: 'What did the Messenger of Allah say?' She said: 'The Messenger of Allah cursed the one who shaves his head, raises his voice in lamentation or rends his garment." (Using translation from Nasāʾī 1867)   

قَالَ رَسُولُ اللهِ ﷺ؟ قَالَتْ بَلَى ثُمَّ سَكَتَتْ فَقِيلَ لَهَا بَعْدَ ذَلِكَ أَيُّ شَيْءٍ؟ قَالَ رَسُولُ اللهِ ﷺ قَالَتْ إِنَّ رَسُولَ اللهِ ﷺ «لَعَنَ مَنْ حَلَقَ أَوْ سَلَقَ أَوْ خَرَقَ»
