Muslims are commanded to act differently from others:

Muslims are commanded to act differently from others:

‘Ubada bin as-Samit said that when God’s messenger ﷺ followed a funeral he did not sit down till the corpse was placed in the grave. On being accosted by a learned Jew and told that that was how they did, God’s messenger ﷺ sat down and said, “Act differently from them.”

(Tirmidhi, Abu Dawud and Ibn Majah, Mishkat al-Masabih 1681)

It's to be noted that the prophet ﷺ immediately sat down when he learnt that the Jews do not sit before burial in the grave-yard, just to be different from them and clearly commanded the Muslims to act differently from the kuffar. 

Similarly, we find many ahadith mentioning to act differently in various things even in seemingly small issues. 

The aim of this is to inculcate a strong sense of separate identity in the Muslims and prevent them from getting mingled up with kuffar in their culture and habits. 

This is very important for the Muslims living as minorities in kaafir lands other wise it is easy to loose one's identity in the melting pot of dominant kaafir and secular cultures.
