The shayatin came to them and turned them from their religion

Muslim relates from the Prophet ﷺ that he told that his Lord said on this day: know that my Lord commanded me to teach you what you did not know of what He taught me this day — every wealth I bestow on a servant is lawful; and I created My servants hanif, all of them; but the shayatin came to them and turned them from their religion, forbade them what I permitted them, and ordered them to associate partners with Me without authority sent down by Me ¹ Muslim 2865.

In this hadith qudsi mankind was created hanif upon monotheism, and it was the shayatin who seduced them away from their religion, swapped the lawful for the unlawful, and introduced associating partners ¹.

From the hadith qudsi of Sahih Muslim; the Jinn & Devils Browser shows it in the devils section ¹.
