Quran 5:103 — The Feast (Al-Ma'edah)

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.

[5:102] Others before you have asked the same questions, then became disbelievers therein.

[5:104] 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?
