Whoever Imitates a People is One of Them
The Prophet of Allah (Sallallaahu `alayhi wa sallam) said:
“Whoever imitates a people is one of them.”
Narrated by Abu Dawood, 3512; classed as saheeh by al-Albaani.
Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him) said: This at the very least indicates that it is haraam to imitate them, although the apparent meaning is that the one who imitates them is a kaafir. Iqtida’ al-Siraat al-Mustaqeem, 1/237.
