The idea of ​​monotheism in the Holy Quran

The idea of ​​divine truth and the idea of ​​the oneness of God is one of the highest thoughts in the history of human existence and the most important of them both mentally and religiously. With its validity, faith is correct and deeds are accepted. The philosophers and prophets have dealt with it, each in his own way. The philosophers have dealt with it in their own rational way, so the paths became saturated with them and people were blinded to the face of what is right. The prophets dealt with it with the inspiration of heaven, so the truth became clear and light spread.
Despite the efforts of philosophers and the prophets, the idea remained an area of ​​research and consideration until Islam came, saying the final word and establishing conclusive evidence and clear proofs of what is correct in this idea.
