O you who acknowledge, do not take as allies those who have taken your system as fun and games from among those who have been given the book before you and the ingrates. Be aware of God if you are those who acknowledge.
Translation endnotes
[5:51-57] Verse 5:57 provides the characteristics of the people of the book, whom we are instructed not to ally ourselves with. Muslims should not ally themselves with those who insult their values or promote hatred against them. Obviously, this instruction is in the context of religious conflict; not in the context of social, personal, or financial relationship. There are righteous people among the people of the book (3:113; 3:199: 5:69). Eating their food or marriage with them is permitted (5:5). Verses 5:57 and 60:7-9 are among the verses that provide us with basic principles in dealing with others.
