The Testimony of Faith (Shahada)
The foundation of faith is the Shahada (Testimony of Faith). This first and most fundamental pillar of Submission is stated clearly in the Quran, exactly as it was revealed to the recipients of previous Scriptures.
The Testimony of Faith in the Torah (Old Testament) reads:
"Hear, O' Israel: the Lord our God, the Lord is One" (Deuteronomy 6:4-5)
The same Testimony is reaffirmed in the New Testament through the words of Jesus:
"The most important one (commandment)," answered Jesus, "is this: 'Hear, O Israel: The Lord our God, the Lord is one.'" (Mark 12:29)
Likewise, the Testimony authorized by God in the Quran confirms the very same truth:
[3:18] GOD bears witness that there is no god except He, and so do the angels and those who possess knowledge. Truthfully and equitably, He is the absolute god; there is no god but He, the Almighty, Most Wise.
Across all Scriptures, the true Testimony contains no name other than the name of God.
First
First and foremost, the only Shahada authorized by God in the Quran is the one stated in 3:18.
This Testimony is not formulated by humans; it is uttered by God Himself, and it is shared by the angels and those who possess knowledge.
Despite this, the majority of Muslims today are not satisfied with the Shahada given in 3:18, and they add to it the words: "and I bear witness that Muhammad is His messenger."
To add any words or names to a Testimony authorized by God is, in effect, to imply that the Testimony given by God in the Quran is incomplete, or that God somehow omitted part of it. Needless to say, God is neither forgetful nor prone to error. We are explicitly told that the Quran is fully detailed (6:114) and that God has left nothing out of the Book (6:38).
We are also commanded clearly in the Quran to follow the Quran alone. As a result, all those who utter a Shahada that includes the name of Prophet Muhammad are violating Quranic law.
Second
When some people are asked why they add a testimony for the Prophet—despite it not being authorized by God in the Quran—they often reply:
"We are only saying that Muhammad is a messenger of God. How can that be wrong when it is a true fact?"
This response reveals a fundamental misunderstanding. The utterance of the Shahada is an act of worship, not merely a statement of fact. By adding a name to the only authorized Shahada in the Quran (3:18), the following violations occur:
1. Violation of Exclusive Worship (6:162–163)
We are commanded to dedicate all acts of worship to God alone, and the Shahada is the very first act of worship:
[6:162-163] Say, "My Contact Prayers (Salat), my worship practices, my life and my death, are all devoted absolutely to GOD alone, the Lord of the universe. He has no partner. This is what I am commanded to believe, and I am the first to submit."
This command is reaffirmed in:
[18:110] Say, "I am no more than a human like you, being inspired that your god is one god. Those who hope to meet their Lord shall work righteousness, and never worship any other god beside his Lord."
2. Rejection of God's Authorized Testimony
Adding to the Shahada constitutes a rejection of the Testimony God Himself provided in 3:18 and implies that what God revealed is incomplete.
3. Failure in the Test of Pure Monotheism (39:45)
[39:45] When GOD ALONE is mentioned, the hearts of those who do not believe in the Hereafter shrink with aversion. But when others are mentioned beside Him, they become satisfied.
Absolute Exclusivity of God in Worship
God's greatness is far beyond human comprehension, which is why we are strictly forbidden from associating anything or anyone with Him:
[4:36] You shall worship GOD alone, and do not set up any idols beside Him.
Notice the precision of the language:
In 4:36: "do not associate anything"
In 18:110: "never associate anyone"
These expressions leave no room for exception. They emphasize that no name—human or otherwise—may be placed next to God's name in any act of worship, including the Shahada (6:162).
This principle is further reinforced in:
[39:2-3] This scripture is revealed from GOD, the Almighty, the Wise. We have sent down to you this scripture, truthfully; you shall worship GOD, devoting your religion absolutely to Him alone. Absolutely, the religion shall be devoted to GOD alone. Those who set up idols beside Him say, "We idolize them only to bring us closer to GOD." GOD will judge them regarding their disputes. GOD does not guide such liars, disbelievers.
Here, God repeats the command to devote all religion exclusively to Him. Ironically, those who idolize the Prophet or members of his family justify their actions by claiming that such practices bring them closer to God—exactly as described in 39:3.
God's response to this claim is decisive:
GOD does not guide such liars, disbelievers. (39:3)
Third
According to the Quranic definition in 2:285, true belief (Iman) consists of belief in:
God
The angels
The Scripture
The messengers
All four are essential for faith. However, no testimony is required from believers except for God alone. We are never commanded to utter a Shahada for the angels, the Scriptures, or the messengers. The only Shahada required is for God.
Some attempt to justify including Muhammad's name by arguing that Jews and Christians rejected him, and therefore Muslims proclaim his messengership. This argument is flawed. Jews and Christians also reject the Quran as the word of God. If sincerity were the motive, consistency would demand an additional testimony such as:
"There is no god but God, and the Quran is the word of God."
Yet no such testimony exists. In reality, the motive is the elevation of Muhammad above all other messengers and the placement of his name alongside God's.
Fourth
The Quran explicitly commands believers not to distinguish between any of God's messengers:
"We do not distinguish between any of His Messengers." (2:285)
Muhammad is indeed a messenger of God—but so are Abraham, Moses, Jesus, David, and others. To single Muhammad out violates this command.
Muhammad himself declared:
[46:9] Say, "I am not different from other messengers. I have no idea what will happen to me or to you. I only follow what is revealed to me. I am no more than a profound warner."
Despite this, many Muslims exalt Muhammad with titles such as:
Sayeduna Muhammad
Sayed Al Khalq
Ashraf Al-Mursaleen
Habib Allah
Such titles contradict the Quran and violate pure monotheism.
If the goal were merely to testify to messengership, why is no one saying:
"There is no god but Allah and Moses is His messenger"?
The inconsistency exposes the true motive: idolization.
Fifth
The Quran identifies another form of testimony—one spoken exclusively by hypocrites:
[63:1] When the hypocrites come to you they say, "We bear witness that you are the messenger of GOD." GOD knows that you are His messenger, and GOD bears witness that the hypocrites are liars.
God deliberately uses "knows" instead of "bears witness" when affirming Muhammad's messengership. This distinction is crucial. Had God said "God bears witness that you are His messenger", it would have constituted a lawful Shahada. But He did not.
The same wording appears in:
[61:5] "...when you know that I am GOD's messenger to you?"
Believers know the messengers; they do not testify to them in worship. The only authorized Shahada remains:
GOD bears witness that there is no god except He (3:18)
Sixth
Finally, the Quran gives a clear criterion to distinguish true believers from idolaters:
[39:45] When GOD ALONE is mentioned, the hearts of those who do not believe in the Hereafter shrink with aversion. But when others are mentioned beside Him, they become satisfied.
The Shahada is a test of sincerity. True believers are content with God's Testimony alone. Those who harbor idols cannot utter it without adding another name.
The Quranic Shahada stands complete, pure, and sufficient—with the name of God alone.
