Al-An'aam 6:136

They assign to Allah a portion of the crops and livestock He created, saying, “This is for Allah” – as they claim – “and this is for our partners [i.e., idols].” But that which is assigned for their partners does not reach Allah, while that which is assigned for Allah reaches their partners[44]. How unfair their judgment is!

[44] It was an Arab heathen ritual to allocate two shares out of their livestock; a share for God and a share for idols. If a portion of God’s share was mixed with that of their idols, they would not deduct it, saying that God is in no need of it. Yet if a portion of their idols’ share fell with that of God’s they would readily cut it and add it on to their idols’ share.

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.

136. And they assign to Allâh a share of the tilth and cattle which He has created, and they say: "This is for Allâh according to their claim, and this is for our (Allâh’s so-called) partners." But the share of their (Allâh’s so-called) "partners" reaches not Allâh, while the share of Allâh reaches their (Allâh’s so-called) "partners"! Evil is the way they judge!

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.
