The Qur’an has 6,236 verses in total (not counting the basmalas at start) with the core message being to worship Allaah alone (Tawhid) without associating any partners in that worship (Shirk). The first pillar of Islaam (Shahadah) and the first pillar of Eemaan (belief in Allaah) are testament to this. The message of the Prophets and Messengers throughout history including that of Noah, Abraham, Ishmael, Isaac, Jacob, Joseph, Moses, Jesus and Muhammad (peace be upon them all) was: “O my people! worship Allah! (alone) You have no other Ilah (God) but Him.”
Here’s a list of some of the many verses in the Qur’an that command the exclusive right and worship of Allaah alone and prohibit the association of any partners along with or besides Allaah:
