The Idolators' worship of others besides Allah and Their vehement rejection of the Ayat of Allah

Allah tells us that the idolators, in their ignorance and disbelief, worship besides Allah others which He has sent down no authority for, i.e., no proof or evidence for such behavior. This is like the Ayah:

وَمَن يَدْعُ مَعَ اللَّهِ إِلَـهَا ءَاخَرَ لاَ بُرْهَانَ لَهُ بِهِ فَإِنَّمَا حِسَابُهُ عِندَ رَبِّهِ إِنَّهُ لاَ يُفْلِحُ الْكَـفِرُونَ

Commentary

لِّكُلِّ أُمَّةٍ جَعَلْنَا مَنسَكًا (For every ummah (religious community) We have appointed a way of worship - 22:67). This sentence has come earlier in almost identical words in verse number 34 of this Surah, but the word مَنسَكً (mansak) conveys a different meaning in each verse. In the earlier verse the words مَنسَكً and نسَكً have been used in the context of the rites of Hajj and mean sacrifice of animals, while in the present verse the word مَنسَكً has been used in the sense of the rules of slaughter or general rules of worship. That is why, unlike the verse 34, the present verse does not have the conjunctive letter ' وَ ' (i.e. 'and' ) in the beginning.
