All praise is due to Allah, and may peace and blessings be upon the Messenger of Allah.
This expression is inappropriate when speaking about Allah, Exalted and Most High, and a Muslim should not describe Allah in this way, even if the intention is to deny imperfection. This is because declaring Allah free of imperfection should be done using the most appropriate and respectful expressions, and the Sunnah generally establishes the attributes of perfection in detail while denying imperfections in a comprehensive manner.
The revealed texts establish Allah’s attributes of perfection in detail, such as knowledge, power, hearing, sight, mercy, and wisdom, while generally declaring Him free of imperfections through comprehensive expressions.
Allah, the Exalted, says:
“There is nothing like unto Him, and He is the All-Hearing, the All-Seeing.” [Ash-Shura 42:11]
He also says:
“Do you know of any similarity to Him?” [Maryam 19:65]
And He says:
“He neither begets nor is born, nor is there to Him any equivalent.” [Al-Ikhlas 112:3–4]
This is among the most complete ways of honoring Allah: His perfection is affirmed in detail, and He is declared free of imperfections through comprehensive expressions.
This does not mean that every denial of an imperfection concerning Allah is forbidden. The Qur’an does deny certain things of Allah, such as His statement:
“And no weariness touched Us.” [Qaf 50:38]
And His statement:
“And your Lord is not unjust to His servants.” [Fussilat 41:46]
However, the negations found in the revealed texts serve a wisdom and imply the affirmation of the opposite attribute of perfection. Denying injustice implies perfect justice, while denying incapacity implies perfect power.
As for someone who begins mentioning ugly or insulting descriptions and then says, “Allah is not such-and-such,” this is not an appropriate way to honor Allah. It may become a form of disrespect and poor etiquette.
The word “stupid” is not appropriate in the context of speaking about Allah, even if the speaker intends to deny ignorance and imperfection.
If the intended meaning is that Allah is not ignorant and that His knowledge is complete and encompasses everything, then this meaning is correct. However, expressing it using the word “stupid” is inappropriate because it is an ugly term that does not befit the majesty of the Lord.
A Muslim should instead say, for example:
“Allah knows everything.”
“Glory be to Allah; He is exalted above every imperfection.”
“Indeed, Allah is All-Wise and All-Knowing; nothing is hidden from Him.”
These expressions affirm Allah’s perfection and declare Him free of imperfection in an appropriate and respectful manner.
The fact that this expression was uttered during anger or a heated discussion does not make it a good expression.
Honoring Allah includes guarding one’s tongue and not making Allah’s names and attributes a subject of argument, anger, mockery, or exaggerated speech.
Allah, the Exalted, says:
“What is the matter with you that you do not attribute to Allah due grandeur?” [Nuh 71:13]
That is, why do you not honor Allah as He deserves to be honored?
Honoring Allah is not merely a matter of belief in the heart; its effects should also appear in a person’s words and actions.
If someone utters this expression without intending to mock Allah or diminish His status, but rather intending to deny ignorance, they should seek Allah’s forgiveness, repent to Him, guard their tongue in the future, and avoid repeating such expressions.
A Muslim should not become trapped in obsessive doubts. Rather, they should repent and replace inappropriate expressions with good, religiously appropriate words.
However, if the statement was intended to mock Allah, ridicule Him, or demean His majesty, this is a different and extremely serious matter that must not be taken lightly.
Saying, “Indeed, Allah is not stupid,” is an inappropriate expression when speaking about Allah and should not be used, even when the intention is to deny imperfection. Allah should be declared free of imperfection using good, religiously appropriate expressions that befit His majesty.
The correct expressions include:
“Allah knows everything, is All-Wise, nothing is hidden from Him, and He is free of every imperfection.”
Whoever has uttered such an expression unintentionally or during anger should seek Allah’s forgiveness, learn to honor Allah through their words, and avoid making speech about Allah part of heated arguments and disputes.
And Allah knows best.
