Read and reflect on verse 2666 from Surah Al-Hajj: And yet they [who claim to believe in Him often] worship [other beings or forces] beside God - something for which He has never bestoweed any warrant ...
وَيَعْبُدُونَ مِنْ دُونِ اللَّهِ مَا لَمْ يُنَزِّلْ بِهِ سُلْطَانًا وَمَا لَيْسَ لَهُمْ بِهِ عِلْمٌ ۗ وَمَا لِلظَّالِمِينَ مِنْ نَصِيرٍ
And yet they [who claim to believe in Him often] worship [other beings or forces] beside God - something for which He has never bestoweed any warrant from on high, and [of the reality] whereof they cannot have any knowledge: and such evildoers shall have none to succour them [on Judgment Day].
