5:104And when it is said to them, “Come to what God has revealed, and to the Messenger,” they say, “Sufficient for us is what we found our forefathers upon.” Even if their forefathers knew nothing, and were not guided?

5:105O you who believe! You are responsible for your own souls. He who has strayed cannot harm you if you are guided. To God is you return, all of you, and He will inform you of what you used to do.
