Whoever resembles a people
مَنْ تَشَبَّهَ بِقَوْمٍ فَهُوَ مِنْهُمْ
Man tashabbaha bi-qawmin fa-huwa minhum.
"Whoever imitates a people becomes one of them."
Narrated by Abdullah ibn Umar. Sunan Abi Dawud 4031
A short reflection
Practical, not paranoid. Dress, speech, manners, allegiance. What you imitate shapes who you become.
