Qur'an 6:136

وَجَعَلُوا۟ لِلَّهِ مِمَّا ذَرَأَ مِنَ ٱلْحَرْثِ وَٱلْأَنْعَـٰمِ نَصِيبًا فَقَالُوا۟ هَـٰذَا لِلَّهِ بِزَعْمِهِمْ وَهَـٰذَا لِشُرَكَآئِنَا ۖ فَمَا كَانَ لِشُرَكَآئِهِمْ فَلَا يَصِلُ إِلَى ٱللَّهِ ۖ وَمَا كَانَ لِلَّهِ فَهُوَ يَصِلُ إِلَىٰ شُرَكَآئِهِمْ ۗ سَآءَ مَا يَحْكُمُونَ

“And they [i.e., the polytheists] assign to Allāh from that which He created of crops and livestock a share and say, "This is for Allāh," by their claim, "and this is for our 'partners' [associated with Him]." But what is for their "partners" does not reach Allāh, while what is for Allāh - this reaches their "partners." Evil is that which they rule.”
