192. 1. A person wrote a letter to Imam Jafar as-Sadiq (p) telling him about a certain group which attributes form and features to God and requested him to explain the true doctrine of Divine Unity.
Imam Jafar as-Sadiq (p) replied: May God be merciful to you. You have asked me about the Oneness of God and the notion which a group holds. Exalted is God, there is nothing like Him and He is All-Hearing and All-Seeing. God is above what is attributed to Him by those who liken God to His creatures, those who tell lies about God. Remember, may God be merciful to you, that in respect of the Oneness of God the true doctrine is what is revealed in the Noble Quran regarding the attributes of God, the Mighty, the Exalted. Keep away from God, the Sublime, all notions of negation and similitude. His existence should never be negated nor should He be likened to anything. He is God, the Established, the Existent. Exalted is He far above what the interpreters attribute to Him. Exceed not the Noble Quran; otherwise you will be stranded even after the exposition of the truth.

193. 2. Imam Zainul Abideen (p) was requested by Abu Hamza, a believer, to explain the concept of the Oneness of God.
Imam Zainul Abideen (p): O Abu Hamza, Any kind of limitations cannot define God. The limitations cannot be attributed to God. The status of our Lord is very high and more sublime than the extent of definitions and attributes. Then how can He who is unlimited be defined by concepts which are themselves limited.
Then the Imam (p) quoted the following verse of the Noble Quran: Vision cannot perceive Him and He perceives all; He is the Subtle, the All-Aware (Q, 6:103).

194. 3. Two persons appeared before Imam Ali ar-Reza (p) and said that during the Night of Ascension, the Prophet Muhammad (p) saw his Lord in a perfect form of a youth of the age of thirty. They said that they also heard that His body up to the navel was hollow and the remaining portion was solid.
Imam Ali ar-Reza (p) went into prostration saying: You are Glorified. They could neither comprehend You nor Your Oneness. Due to this (ignorance) they have described you by wrong attributes. Glorified are You. Had they comprehended You, they would have described You as You have described Yourself. You are Glorified. How their souls have induced them to liken you to others. God, I shall never ascribe to You any attributes save those You have Yourself ascribed to Your Supreme Self and I shall never liken You to Your creatures. You are the possessor of all goodness. Do not include me among the wrongdoers.
The Imam (p) then addressed the two persons: Whatever and however you imagine, you imagine something other than God. We the progeny of Prophet Muhammad (p) represent the Golden Mean which is lost to transgressors and those who lag behind cannot overtake us.
The Imam (p) further explained: God is far above the level of having the attributes of His creations …

195. 4. Imam Zainul Abideen (p): If all the dwellers in the heaven and on the earth gather together to praise God in all His Glory and Greatness, they will not be able to do so.

196. 5. A person wrote to Imam al-Hasan al-Askari (p) as follows:
We have come across some of your followers who differ in the matter of the Unity of God. Some say that He has body and some maintain that He has a shape.
The Imam (p) wrote back in reply: Glory be to God, who can neither be defined nor qualified. Nothing is like Him and He is All-Hearing and All-Knowing.
According to another version of the tradition, the last words of the Imam (p) were ‘All-Seeing.’

197. 6. On the topic of the Oneness of God, Imam Musa al-Kazim (p) wrote:
Verily, God is High and Mighty and Sublime and far higher than the realities of His attributes which can be fully comprehended. Ascribe to Him only those attributes which He has assigned to Himself and refrain from qualifying God with anything besides those attributes.

198. 7. Imam Musa al-Kazim (p) was asked regarding the attributes of God.
The Imam (p): Do not exceed the limits set by the Noble Quran.

199. 8. A person wrote to Imam Musa al-Kazim (p) about the difference of opinion which existed among people regarding the Oneness of God.
The Imam (p): Glory be to Him who has no limitations and cannot be defined. Nothing is like Him and He is All-Hearing and All-Seeing.

200. 9. In a letter to Imam al-Hasan al-Askari (p) on the topic of the Oneness of God, a believer wrote:
People who live around us differ among themselves regarding the topic of the Divine Unity. Some of them say that He has a body and some of them maintain that He has a form (shape).
Imam al-Hasan al-Askari (p): Glorious is He who is infinite and who cannot be defined or qualified. He does not resemble anything and nothing resembles Him. He is All-Hearing, All-Seeing.

201. 11. Imam Jafar as-Sadiq (p): Verily, God cannot be defined. And how can He be defined when He himself has said in Noble Quran: No just estimate of God do they make (Q, 6:91). In whatever manner He is defined, He will be greater than that.

202. 12. Imam Jafar as-Sadiq (p): Verily, God is Great and Sublime. People cannot describe His attributes and they cannot describe the sublimity of His Greatness. Vision cannot take Him in its grip and He takes the eyes in his grip. He is All-Subtle, All-Aware (Q, 6:103). States, whereabouts or conditions are not applicable in His case. How can He be described when the concepts and connotation of description have been created by Him, so that it became conception and modality that came into being and we understood to describe Him in terms of His space since He himself has created the space so that it came into being and we knew the space through the space which He had fixed for sense of direction so that the sense of direction came into being and we know the directions through the direction which He has fixed for us. Therefore, God, the Hallowed, the Most High is at every place but is out of everything. Vision sees him not but he perceives. There is no god save Him, the Sublime, the Great and He is the All-Subtle, All-Aware.
