Prophet Jonah - 10:35
"Say, "Which of your associates can guide to the truth?"Say, "Allah guides to the truth. Who is more worthy to be obeyed, He who guides to the truth, or he who cannot find the truth unless he is guided to the truth? How do you judge?"
How does Allah guide to the truth?
The Sandhills/46:30
"O our people,"they said, "we have listened to a Book sent down after Moses, confirming what was before him. It guides to the truth and to a straight path."
The Cow/2:213
Mankind were a single community. Allah sent messengers as bearers of glad tidings and warners and sent down with them the Book containing the truth so that they might judge between the people in matters wherein they differed. But those who were given the Book disputed about it out of envy among themselves after clear proofs had come to them. But Allah, by His permission, brought the believers to the truth about which they differed. Allah guides whom He wills/whosoever He wills.
The Table Spread/5:19
"People of the Book! Our apostle has come to you after a period of gap between the apostles, and he is telling you the truth so that you may not say: "There has not come to us a bearer of glad tidings and a warner". Behold, a bearer of glad tidings and a warner has come to you. Allah is the Almighty."
The Table Spread/5:48
We have sent down to you this Book, which confirms the previous Books and replaces them, as a comprehensive truth, so judge between them by what Allah has sent down to you. Do not leave the truth that has come to you and follow their whim. We have appointed for each of you a law and a method, and if Allah had willed, He would have made you all one people. But He tests you with what He has given you. Compete in good deeds. To Allah is the return of all of you. He will inform you of the matters on which you differ.
The Repentance/9:33
He has sent His messenger with guidance and the true religion so that He may make it superior to all religions. Even if the idolaters do not wish it.
Prophet Jonah/10:82
Allah fulfills the truth by His words. Even if the guilty dislike it.

"And declare: "The truth has come and the false has disappeared. Falsehood is doomed to perish."

Indeed We have sent it down and it has come down with the truth. And We sent you only as a bearer of glad tidings and a warner
The Prophets/21:18
Nay, We throw the truth upon falsehood and it crushes and destroys it. Woe to you for what you ascribe.
Sheva/34:49
"Say, "The truth has come, and falsehood can neither start a new thing nor repeat it."
Council/42:24
"Do they say, "Has he fabricated a lie about Allah"? If Allah wills, He can seal your heart. Allah erases falsehood and establishes truth in His words. He knows the most secret thoughts."

Because those who disbelieve follow falsehood and those who believe follow the truth from their Lord. This is how Allah exhibits the state of the people.
