Whoever imitates a people is one of them

The Prophet (may Allah's peace and blessings be upon him) informs that whoever imitates some people - disbelievers, sinners, or righteous - by engaging in any of their peculiar traits, such as their creeds, acts of worship, or habits, becomes one of them. This is because outward imitation of them leads to inward imitation.

In fact, imitation of any people indicates admiration of them, and it may result in loving, respecting, and inclining toward them, which may also prompt a person to even imitate them inwardly and in their worship - Allah forbid.
