Quran 6:115 — Livestock (Al-An'am)

The word of your Lord is complete, in truth and justice. Nothing shall abrogate His words. He is the Hearer, the Omniscient.

[6:114] Shall I seek other than GOD as a source of law, when He has revealed to you this book fully detailed? Those who received the scripture recognize that it has been revealed from your Lord, truthfully. You shall not harbor any doubt.

[6:116] If you obey the majority of people on earth, they will divert you from the path of GOD. They follow only conjecture; they only guess.
