Surah Yunus, Ayat 18

Ayat 18. And they worship besides Allah things that hurt them not, nor profit them, and they say: "These are our intercessors with Allah." Say: "Do you inform Allah of that which He knows not in the heavens and on the earth?" Glorified and Exalted be He above all that which they associate as partners with Him!

Hazrat Abu Abdullah bin Tariq bin Ashyam (May Allah be pleased with him) reported: Messenger of Allah  [SAWW](PBUH) said, "He who professes La ilaha illallah (There is no true god except Allah), and denies of everything which the people worship besides Allah, his property and blood become inviolable, and it is for Allah to call him to account". [Muslim Hadith # 34].

Lesson : as mentioned above in Surah Yunus Ayat 18. "He (Allah is) above all that which they associate as partners with Him!". This Hadith highlights two point of importance without them Faith is incomplete, first there is no true God except Allah (SWT), and second denial of everything which the people worship besides Allah (SWT).
