It is the duty of all faithful...

It is the duty of all faithful, sincere, conscientious, and rational Christians, Jews, and Muslims to cooperate against evil, join forces in the ideological battlefield, and work together in unity and harmony. This unity must be based on the principles of love, respect, acceptance, and cooperation. The urgency of the situation must be remembered, and disputes, arguments, and all other human-made (and therefore artificial) barriers between people must be abandoned.

When we look at the Old Testament, the New Testament, and Qur'an, we see that they all recommend using friendly words and conducting oneself properly and with dignity. The Christians' attitude toward others is described, as follows, in the Bible: … always try to be kind to each other and to everyone else. (1 Thessalonians 5:15) … to slander no one, to be peaceable and considerate, and to show true humility toward all men.

(Titus, 3:2) The Torah states that Jews must treat people well: Seek good, not evil, that you may live. Then the LORD God Almighty will be with you, just as you say He is. Hate evil, love good; maintain justice in the courts... (Amos, 5:14-15) In the Qur'an, God states the importance of virtue, righteousness, and responding to evil with goodness and commands Muslims to approach Christians and Jews in the appropriate manner.

The Qur'an clearly states that the People of the Book are closer to Muslims than idolaters or atheists. Even though some Jewish and Christian beliefs and practices no longer accord with the original divine revelations, their revealed books still contain moral values based on divine revelation and a code of good and evil, which is why their food is halal (lawful) for Muslims.

Likewise, Muslim men are allowed to marry Jewish and Christian women, for: Today all good things have been made halal [lawful] for you. The food of those given the Book is also halal for you, and your food is halal for them. So are chaste women from among the believers and chaste women of those given the Book before you, once you have given them their dowries in marriage, not in fornication or taking them as lovers.

But as for anyone who rejects faith, his actions will come to nothing, and in the Hereafter he will be among the losers. (Qur'an, 5:5) These rules show that Muslims and the People of the Book can establish good relations among themselves through marriage and the sharing of food, both of which enable the formation of warm human relationships and tranquil togetherness.
