The 9/11 has further widened the gulf between the followers of two main faiths of the world. Although Islam like Christianity or any other religion has nothing to do with the acts of few desperate heretics [takfiri in this case] using terror and violence as a tool to achieve their political objectives under the garb of religion. However now a days it is trendy to claim that the God of Muslims is different to the God of Christians. The rhetoric of the myth gave a tacitly playful acknowledgement of the existence of two Gods, but the question was understood as not asking about the existence of two actual Gods, but whether or not Christians and Muslims were imagining the same being; the entity who would be the one true God. But it is not that simple either, because one may say that he believes in the one true God, who happens to be a wrestling with some one, or walking. One may talk of the “one true God” and mean the same thing as others think as far as the term itself goes, but it does not highlight the characteristics of God, which they would not agree on. Hence the question should not be phrased causally as; “Do Christians and Muslims worship the same God?” (as we can agree there could only be one God), but instead: “Do Christians and Muslims perceive a God with either identical or similar enough characteristics to be called the same Being?”
Generally people tend to relegate the divine to an object of speculation due to their knowledge based upon intellect and common sensual perceptions. Generally people have no doubts about anything that they can perceive through their senses, which is accepted as the fundamental truth. However, if one is in the desert at noon and see a lake in the distance, but only finds sand when reaches that area, what appeared to be a lake turned out to be mirage. Likewise if a pencil is placed in a glass of water it will look as if it is broken, though in actual fact it is not. In a late night gathering, if the people start discussing about the supernatural-ghosts, while traveling back home, many get so carried away that they feel as if a ghost or demon is following them, whereas in reality it is just an illusion. A magician will produce strange objects which seem to be real, even though they are not. Hence human senses can be deceptive, but does this mean that people should doubt the existence of something they can feel? Quite the reverse because if they doubt what they see, hear and feel, there will be a conflict between fact and fantasy that will eventually drive them nuts. But another condition may be added here about obtaining knowledge – meaning, certainty regarding the existence of what is sensed. The mind may misjudge something the first time it perceives it. For example, it may think a mirage is a lake, but the second time it sees it will not make the mistake. Similarly it will soon realize that even though the pencil on the glass of water looks broken, in fact it is not. The various ways in which the senses delude us are limited and easy to recognize. This includes the tricks that magicians perform and the circus activities.
Any theological exposition which carries the idea of God, somewhat frivolously, reshaping God as an object to be discussed, is against God’s transcendence [beyond the ordinary range of human perception]. It must be appreciated that such approach may lead to erroneous conclusions. Consequently when people articulate God in such a manner, they do not speak of God, but of an idol, with what ever ‘name’ they choose. However much one may wish to accurately know of God, the divine is something that cannot be comprehended by humans in totality due to limitations of human perception, but allegory makes the incomprehensible as comprehensible. Thus many people may perceive God, in their own way depending upon his [or her] level of intellect, perceptions and knowledge, though openly may be claiming to follow a specific creed. Thus the question as to who is right and who is wrong depends upon the parameters and perceptions.
Defining God & Attributes:
“Hence, do not coin any similitude for God! Verily, God knows [all], whereas you have no [real] knowledge.”[Qur’an;16:74]
Since “definition” is, in the last resort, equivalent to a delimitation of the qualities of the object thus to be defined in relation to, or in comparison with, another object or objects: God, however, is “sublimely exalted above anything that men may devise by way of definition “Do not blaspheme against God by regarding anyone or anything as comparable with Him, or by trying to define Him in any terms whatsoever”
“And yet, some [people] have come to attribute to all manner of invisible beings a place side by side with God -although it is He who has created them [all]; and in their ignorance they have invented for Him sons and daughters! Limitless is He is His glory, and sublimely exalted above anything that men may devise by way of definition:”[Qur’an:6:100]
Utterly remote is He from all imperfection and from the incompleteness which is implied in the concept of having progeny. The very concept of “definition” implies the possibility of a comparison or correlation of an object with other objects; God, however, is unique, there being “nothing like unto Him” (Qur’an;42:11) and, therefore, “nothing that could be compared with Him” (Qur’an;112:4) – with the result that any attempt at defining Him or His “attributes” is a logical impossibility and, from the ethical point of view, a sin. The fact that He is undefinable makes it clear that the “attributes” (sifat) of God mentioned in the Qur’an do not circumscribe His reality but, rather, the perceptible effect of His activity on and within the universe created by Him.

Brief Description of Names of God & His Titles in Bible:
Monotheism has been clearly emphasized in Bible, the verse from the book of Deuteronomy contains an exhortation from Moses (peace be upon him):”Shama Israelu Adonai Ila Hayno Adna Ikhad“. It is a Hebrew quotation which means: “Hear, O Israel: The Lord our God is one Lord”(Deuteronomy;6:4, Isaiah;43:11, 45:5,46:9). Jesus (peace be upon him) also said: “Shama Israelu Adonai Ila Hayno Adna Ikhad ”[“Hear, O Israel: The Lord our God is one Lord”](Mark;12:29), “..There is none good but one, that is, God..”(Mathew;19:17). Qur’an says: “Your God is one God; there is no one worthy of worship except Him, the Compassionate, the Merciful.” (Qur’an;2:163). The monotheism in Islam is called Tawhid in Arabic; Allah, the One and Only God. Allah says:, “Say: He is Allah the One and Only; God the Eternal, the Uncaused Cause of All Being ; He begets not, and neither is He begotten; And there is nothing that can be compared with Him.”(Qur’an;112:1-4). Attributes of Allah has been mentioned at many places in Qur’an some references are Qur’an; 2:255, 59:22-24, 42:11-12, 11:6, 6:59, 31:34, 4:164, 7:143, 31:27, 6:115, 4:87, 2:133). Similarly according to Bible, God says: “Thou shalt have no other gods before me.” “Thou shalt not make unto thee any graven image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth:” “Thou shalt not bow down thyself to them, nor serve them: for I the Lord thy God am a jealous God.”(Exodus; 3:15, 20:3-5, Deuteronomy 5:7-9, 1Timothy;2:5).
Jesus cried out in a loud voice: “Eli, Eli, lema sabachthani?” (“My God, my God, why have you forsaken me?”).[Mathew 27:46., Mark 15:34]
