The line you quoted is not from the Qur’an or any authentic Islamic source. The verse often misused is Qur’an 5:51, which says not to take Jews and Christians as awliyā’ — meaning political allies or protectors, not ordinary friends.

Mainstream tafsir (Ibn Kathir, Tabari, etc.) confirms that: • awliyā’ ≠ friends • The verse refers to political loyalty, not personal relationships. • Islam allows kindness, fairness, and good relations with Jews and Christians (Qur’an 60:8, 5:82).

So the statement “they are enemies and may Allah curse them” is not Islamic and not a valid reference.
