FOR DISPUTES TAKE THE BEST WAY
“And dispute not with the people of the Book, except in a way that is the best, unless it be with those of them who have oppressed.”
This verse implies that in our discussion or dispute with them, we must be polite and speak friendly, using reasonable expressions. We should not speak loudly and with anger. There should be no abuse and irony, and we always have to speak the truth.
In this case too, there is an exception. Such an Islamic behaviour is only fit for those who are not oppressing; and where the other party does not think it to be a weak point of the Moslems. When your counterpart is a stubborn, fanatic, and bold arrogant; what else can you do?
Your main and reliable logic in your arguments with the people of the book can be that:-
“We believe in what has been sent down to you from Allah, and also to that which has been sent down to us from the Lord, because our God and your God is one and to Him we have submitted.”
The Glorious Qurän has been sent down on the basis of the Oneness of God, the Oneness of Message of all the apostles, and on the unconditioned submission to the will of God, which is called Islam. These principles are what they have found it in their own Scriptures, and have heard it through successive witnesses from the tongue of their apostles.
Then it is referred to an undeniable reason that proves the truthfulness, and prophethood, of our prophet:-
