It is the words of god himself and the divine revelations that are written in the Quran. Muslims are monotheistic and adhere strictly to certain religious practices. One has only to believe that There is no god but Allah and Mohammed is his Prophet to be a true Muslim. Friday is an important holy day. The design and the order of the universe reveals the unity of god.
Every creature has a definite and defined nature.
Quran declares man to be the noblest of all creation and all nature is made subservient to man. Human nature is considered to be frail and faltering and viewed as rebellious and full of pride. Pride is a cardinal sin. On the Last day, when the world will come to an end, the dead will be resurrected and a judgement on every person in accordance with his deeds will be pronounced. Muslims do not believe in idol worship and go to a mosque to offer prayers.
