Quran 6:137 — Livestock (Al-An'am)

Thus were the idol worshipers duped by their idols, to the extent of killing their own children.* In fact, their idols inflict great pain upon them, and confuse their religion for them. Had GOD willed, they would not have done it. You shall disregard them and their fabrications.

[6:136] They even set aside a share of GOD's provisions of crops and livestock, saying, "This share belongs to GOD," according to their claims, "and this share belongs to our idols." However, what was set aside for their idols never reached GOD, while the share they set aside for GOD invariably went to their idols. Miserable indeed is their judgment.

[6:138] They said, "These are livestock and crops that are prohibited; no one shall eat them except whomever we permit," so they claimed. They also prohibited the riding of certain livestock. Even the livestock they ate, they never pronounced GOD's name as they sacrificed them. Such are innovations attributed to Him. He will surely requite them for their innovations.
