“Worship Allah, and avoid false deities!”

One GOD

And ask whom We sent before you of Our Messengers: “Did We ever appoint  gods to be worshiped besides the Most Gracious?”  – Quran 43:45.

All the Messengers called the people to worship GOD Alone, with no partner nor associate, and they forbade the worship of idols and false gods: 

“For We assuredly sent among every people a messenger (with the command) ٱعۡبُدُواْ ٱللَّهَ وَٱجۡتَنِبُواْ ٱلطَّـٰغُوتَ‌ۖ

“worship Allah, and avoid false deities;” Quran 16:36.

 

“All the Messengers called their people to the worship of Allah (GOD) alone with no partner or associate, and they forbade the worship of false idols and false gods;” Tafsir ibn Kathir.
