The most fundamental concept of Islam and the fountainhead of all its other principle and practices is unity of God (Tawhid). Islam is monotheism in its purest form, and the logic of pure monotheism is the thread which runs through the entire fabric of the Islamic way of life.

Islam teaches a fundamental difference between Allah, the Creator and that which He has created. The sky, the moon, the stars, the harmony and perfection of the natural world, the grace and beauty of the human body and the excellence of the human mind, the alteration of day and night, the change of the seasons, and the mystery of life and death all point to something beyond, greater than themselves. To the believer these are all signs (ayaat) of Allah. And yet Islam teaches that Allah is not to be likened to anything which he has created. He is All-Powerful, All Knowing; He is beyond any perfection, the fulfillment of all Perfection. Yet He is not a substance nor is He like any of His creatures. He is not a far-away and distant God, nor is He an unapproachable ideal. He is All-Kind, All-Merciful and All-Compassionate.

Islam teaches that Allah is eternal, He was not Himself begotten, nor has He, in turn, begotten a son or a daughter. Islam rejects the concept of the incarnation of God, which is found in Hinduism, Christianity and other religions, and believes that the concept of incarnation limits the concept of God and destroys the believer's conviction of God's dynamic Being.

The Quran describes Allah as perfect and active: "Allah: There is no God but He, The Living, the Everlasting. Neither slumber overtakes him nor sleep. To Him belongs all that is in the heavens and all that is in the Earth. Who can intercede with Him except by His permission? He knows what lies before them, and what is behind them, and they encompass nothing whatever of His knowledge except as He wills. His throne includes the heavens and the earth, and He never wearied of preserving them, for He is the Sublime, the Mighty." [2:155].

Islam rejects the notion that Jesus (peace be upon him) was the Son of God. Rather it honors and respects him as one of Allah's great messengers and prophets to the Children of Israel.

Islam rejects the concept of trinity and considers it a contradiction of pure monotheism. It also rejects the argument of some Christians that God made Himself incarnate in Jesus (peace be upon him) so that God could be known by men, and the argument that Jesus (peace be upon him) dies on the cross for mankind's sins. To begin with, Islam believes that man can come to know Allah and feel close to Him by means of proper prayers, fasting, charity, pilgrim age, and righteous deeds. The very practice of Islam is meant to purify the believer's soul and to bring him close to Allah. With regard to the second argument, Islam teaches that no human being can bear the burden of another's responsibility. Allah is very aware of our human weakness and imperfection. He does not condom us because we are created imperfect; rather He guides us to self-perfection and He forgives us and showers His mercy upon us when we fail and then ask His forgiveness sincerely.

Muslims believe in the divine origin of the Old and New Testaments although Muslims doubt the historical authenticity of some parts of the Old and New Testaments and do not believe them to be exact representations of what Allah originally revealed. The Quran upheld this view of the text of the Old and New Testaments hundreds of years ago, and, in recent years, this view has been upheld by textual studies of Biblical Scholar. . Muslims believe in the Angels of Allah and His Prophets, Peace be upon them. They believe in the resurrection of the dead at the end of the world; they believe in the coming of the Day of judgement and eternal life in the Heaven or Hell.

Although Muslims believe that Allah is All Powerful And maintains complete control over His creations, they also believe that Allah has created man with free will and the ability to choose and act and that Allah is just in making man morally responsible for what man does during his life time. It is false to say that Islam teaches its followers to resign meekly and passively to whatever to fight against wrong and oppression and to strive for the establishment or righteousness and justice.
