Logical argumentation against polytheism

ءَأَتَّخِذُ مِن دُونِهِۦٓ ءَالِهَةً إِن يُرِدْنِ ٱلرَّحْمَـٰنُ بِضُرٍّ لَّا تُغْنِ عَنِّى شَفَـٰعَتُهُمْ شَيْـًٔا وَلَا يُنقِذُونِ

Should I take other than Him [false] deities [while], if the Most Merciful intends for me some adversity, their intercession will not avail me at all, nor can they save me?

أَعِندَهُۥ عِلْمُ ٱلْغَيْبِ فَهُوَ يَرَىٰٓ

Does he have knowledge of the unseen, so he sees?
