Quran 6:136 — Livestock (Al-An'am)

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.

[6:135] Say, "O my people, do your best, and so will I. You will surely find out who the ultimate victors are." Certainly, the wicked will never succeed.

[6:137] 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.
