Al-An'am - 6:136

وَجَعَلُواْ لِلّهِ مِمِّا ذَرَأَ مِنَ الْحَرْثِ وَالأَنْعَامِ نَصِيبًا فَقَالُواْ هَـذَا لِلّهِ بِزَعْمِهِمْ وَهَـذَا لِشُرَكَآئِنَا فَمَا كَانَ لِشُرَكَآئِهِمْ فَلاَ يَصِلُ إِلَى اللّهِ وَمَا كَانَ لِلّهِ فَهُوَ يَصِلُ إِلَى شُرَكَآئِهِمْ سَاء مَا يَحْكُمُونَ
[6:136]
And they set apart a portion for Allah out of what He has created of tilth and cattle, and say: This is for Allah-- so they assert-- and this for our associates; then what is for their associates, it reaches not to Allah, and whatever is (set apart) for Allah, it reaches to their associates; evil is that which they judge.
Out of what Allah hath produced in abundance in tilth and in cattle, they assigned Him a share: they say, according to their fancies: "This is for Allah, and this" - for our "partners"! but the share of their" partners "reacheth not Allah, whilst the share of Allah reacheth their "partners" ! evil (and unjust) is their assignment!
They assign unto Allah, of the crops and cattle which He created, a portion, and they say: "This is Allah's" - in their make-believe - "and this is for (His) partners in regard to us." Thus that which (they assign) unto His partners in them reacheth not Allah and that which (they assign) unto Allah goeth to their (so-called) partners. Evil is their ordinance.
