It does say a lot of bad things (to put it extremely mildly) about people worshiping other deities, especially idols, though.
According to the four Schools of Jurisprudence in the Sunnis and the Ja'fari Schools of Jurisprudence in the Shias Islamic law is derived from the following sources: - Quran and Quranic exegesis - Ahaadith (prophetic traditions) - Ijmaa' (consensus) - Qiyaas (analogy - limited use cases and remit)
This is a ruling that is held by each of the Schools of Jurisprudence in the Sunnis and the Ja'fari School of Jurisprudence of the Shias.
As a side note the modern day Salafis/Wahabis/Ahlul Hadith literally interpret the Quran and Ahaadith (Prophetic Traditions) which is how they reach rulings that differ from the accepted Schools of Jurisprudence that have had millions of scholars over centuries work together.
Literal taking of religious texts is generally incompatible with moderm civilised society
