Islam is a monotheistic religion. Islam means submission to Allah (or God in English and same God worshiped in Christianity and Judaism) as the one and only one God with no partner, no companion, no son, no father, no associate, and no equivalence. Allah do not forgive who worship partner to Him.
Muslims worship only the One God (whose prophets are Adam,..., Noah,..., Abraham, ..., Moses, ..., Jesus, and Muhammad; peace be upon them). Muslims do not believe in praying to any prophet or saint or claimed holy person at all. They worship the One unseen God who has no partners at all. No father, no mother and no offspring. He is the Only God.
