To thee I return and I am the first one to believe in you.
To thee I return and I am the first one to believe in you." (Holy Qur’an, 7:143). And by such incidents it was proved that God can never be seen. We believe that our Islamic traditions denoting the observance of God, aim at seeing Him by the mind and by the heart, and not by the sense of vision of the eyes at all. In one of his sermons collected in the famous book ‘Nahjul Balagha’, Imam ‘Ali (a.s) says: "Eyes cannot see Him, but He can be seen by the realities of Faith".
We believe that the attributes of the creatures, such as: place, direction, material body, and physical observance should not be ascribed to God. If done so, it shall lead to polytheism, and remoteness from the true knowledge of Him, who is above all, and nothing is similar to Him. Monotheism is The Very Soul of All the Islamic Commandments We believe that one of the most important subjects relating to the knowledge of God is monotheism, i.e. the belief that there is only one God.
As a matter of fact monotheism ( tawhid ) is not only a principle of the religion, but the most important of Islamic tenets. It is the very soul and the base of all the Islamic ideas and beliefs. We can say that the roots, as well as the branches of Islam take their forms from the monotheism. The ‘Unity’ and ‘Oneness’ is a general topic of conversation everywhere and in every field; unity of God's essence, His attributes and actions.
In other words, also the unity of prophets and their teachings, the unity of the law, qiblah and the books, and also the unity of Muslims through their brotherhood and the unity of the resurrection day. From this point of view the Holy Qur’an declares polytheism as an unforgivable sin: "Allah does not forgive those who set up partners with Him, but He may forgive any sin less than that, of whom he wills.
He that sets up co-sharers with Allah is guilty of a sin which is most heinous indeed." (Holy Qur’an, 4:48). "It has already been revealed to you as it was revealed to those before you that: "If you join gods with Allah, your deeds shall be fruitless, and you surely will be one of those who loose. (All spiritual goodness).” (Holy Qur’an, 39: 65).
The Branches of Monotheism We believe that monotheism ( tawhid ) has many branches among which four are the most important ones: A) The Unity of Essence His absolute Holy Essence is one, indivisible, and no one is similar or like unto him.
