Warning about imitating other nations

عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ:‏ لَتَتْبَعُنَّ سَنَنَ مَنْ كَانَ قَبْلَكُمْ شِبْرًا شِبْرًا وَذِرَاعًا بِذِرَاعٍ، حَتَّى لَوْ دَخَلُوا جُحْرَ ضَبٍّ تَبِعْتُمُوهُمْ‏‏.‏ قُلْنَا: يَا رَسُولَ الله الْيَهُودُ وَالنَّصَارَى قَالَ:‏ فَمَنْ‏‏

Hazrat Abu Sa‘id al-Khudri^ra narrated, “The Prophet^sa stated, ‘You will follow the customs and traditions of those before you, inch by inch and arm’s length by arm’s length, to the extent that if they were to enter a lizard’s burrow, you would follow them into it.’ We asked, ‘O Allah’s Messenger^sa, do you refer to the Jews and Christians?’ He replied, ‘Who else?’”
