Asalaam Alaykum,
Here are a couple of hadiths about Imitating the kuffar...
Peace and blessings be upon our Prophet Muhammad (SAWS) who said, "I was sent with the Sword in the waning of the Hour until Allah Alone is worshipped without any partners, and He placed my sustenance beneath the shadow of my spear and He placed disgrace and belittlement on he opposes my orders and he who imitates a people(Ahmad, Sahih)
Whoever imitates people is one of them. (Narrated by Abu Dawood).
It was narrated from Abu Saeed al-Khudri (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: You will certainly follow the ways of those who came before you hand span by hand span, cubit by cubit, to the extent that if they entered the hole of a lizard, you will enter it too. We said: O Messenger of Allaah, (do you mean) the Jews and the Christians? He said: Who else? Narrated by al-Bukhaari, 1397; Muslim, 4822
It was narrated that Abd-Allaah ibn Umar said: The Prophet (peace and blessings of Allaah be upon him) said: Whoever imitates a people is one of them. Narrated by Abu Dawood, 3512; classed as saheeh by al-Albaani in Irwa' al-Ghaleel, 2691.
Shaykh al-Islam Ibn Taymiyah (may Allaah 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, 237.
