Al-'Ankabut 29:46

Wala tujadiloo ahla alkitabiilla billatee hiya ahsanu illa allatheenathalamoo minhum waqooloo amanna billatheeonzila ilayna waonzila ilaykum wa-ilahunawa-ilahukum wahidun wanahnu lahu muslimoon

And do not argue with the People of the Scripture except in a way that is best, except for those who commit injustice among them, and say, "We believe in that which has been revealed to us and revealed to you. And our God and your God is one; and we are Muslims [in submission] to Him."

Do not debate with the people of the Book unless it is in the best manner, except with those of them who commit injustice. And say, “We believe in what is sent down to us and sent down to you, and our God and your God is One, and to Him we submit (ourselves).”
