Quran 5:104 — The Feast (Al-Ma'edah)

When they are told, "Come to what GOD has revealed, and to the messenger," they say, "What we found our parents doing is sufficient for us." What if their parents knew nothing, and were not guided?

[5:103] GOD did not prohibit livestock that begets certain combinations of males and females, nor livestock liberated by an oath, nor the one that begets two males in a row, nor the bull that fathers ten. It is the disbelievers who invented such lies about GOD. Most of them do not understand.

[5:105] O you who believe, you should worry only about your own necks. If the others go astray, they cannot hurt you, as long as you are guided. To GOD is your ultimate destiny, all of you, then He will inform you of everything you had done.
