Quran 22:54 — Pilgrimage (Al-Hajj)

Those who are blessed with knowledge will recognize the truth from your Lord, then believe in it, and their hearts will readily accept it. Most assuredly, GOD guides the believers in the right path.

[22:53] He thus sets up the devil's scheme as a test for those who harbor doubts in their hearts, and those whose hearts are hardened. The wicked must remain with the opposition.

[22:55] As for those who disbelieve, they will continue to harbor doubts until the Hour comes to them suddenly, or until the retribution of a terrible day comes to them.
