Assalam o Alaikum Warahmatullahi Wabarakatuhu. May peace mercy and blessings of God (ALLAH) be on all of you.
ALLAH says in the Quran in chapter 3 verse 64:
Say, "O People of the Scripture, come to a word that is equitable between us and you - that we will not worship except Allah and not associate anything with Him and not take one another as lords instead of Allah..."
The equitable word between us is that we should worship none but one true God and it's mentioned in most of the religious scriptures.
