What is the evidence from the Qur'an and Sunnah regarding the prohibition of Muslims imitating disbelievers?

The Islamic legislation prohibited Muslims from imitating disbelievers in their acts of worship, festivals, and specific attire. This is a fundamental principle in Islamic law. This prohibition is based on evidence from the Holy Quran and the Prophetic Sunnah. From the Quran, there are verses that forbid following the desires of those who do not know, call for not imitating the People of the Book in their hardened hearts, and prohibit imitating them in words and actions. As for the Prophetic Sunnah, there are narrations that emphasize this meaning, such as the saying of the Prophet (peace be upon him): "Whoever imitates a people is one of them." He also commanded to differ from the Jews and Christians in dyeing grey hair, forbade wearing the clothes of disbelievers, commanded to differ from the polytheists in beards and mustaches, rejected the trumpet and bell because they are practices of the Jews and Christians, forbade praying during the times when disbelievers prostrate to the sun, and intended to fast the ninth day with the tenth, differing from the Jews in fasting Ashura. All of this confirms that differing from disbelievers and avoiding imitation of them is among the objectives of Islamic law.
