Islam is absolutely clear that there is no God but Allah. There is no room in Islam for God to have partners of any kind.

In the Quran Allah says �Allah. There is no god but He,-the Living, the Self-subsisting, Supporter of all. No slumber can seize Him nor sleep. His are all things in the heavens and on earth. Who is thee can intercede in His presence except as He permitteth? He knoweth what (appeareth to His creatures as) before or after or behind them. Nor shall they compass aught of His knowledge except as He willeth. His Throne doth extend over the heavens and the earth, and He feeleth no fatigue in guarding and preserving them. For He is the Most High, the Supreme (in glory).� Chapter-2: Bakarah-The Cow

Allah Almighty is the ONLY creator and sustainer of the Universe.

All prophets, since the beginning of time have preached the same message of Tawhid (belief in the oneness of Allah. Unfortunately these messages brought by the prophets have been changed, diluted and misinterpreted.

Unlike Christianity, which says that Man is created in God's likeness, Islam teaches us that God cannot be characterized in human form. Allah, the creator, is of course, different from his creation.

�In the name of God, the All-Merciful, the All-Compassionate.
Say (O Muhammad): He is God, the One, Unique. God is the Self-Sufficient (Who needs no one and Whom everyone else needs). He has not begotten, nor has been begotten, and there is none equal to Him.�

Uthman ibne Affan (RA) - Uthman the son of Affan - narrates that the Prophet Muhammad (Peace and Blessings Of Allah Be Upon Him) "He who dies knowing (and believing) that there is none worthy of worship besides Allah, will enter Paradise." Muslim

Ali (RA) that Nabi (SAW) said in a Hadith Qudsi that Allah Almighty says "Indeed I am Allah, there is none worthy of worship except Me; he who acknowledges My Oneness enters My fortress, and he who enters My fortress is safe from My Punishment."

Jabir ibne Abdullah (RA) said: "I heard the Prophet (SAW) saying 'He, who meets Allah, not ascribing any partner to Him, enters Paradise. And he, who meets Allah ascribing a partner to Him, enters the Fire." MUSLIM
