Praise be to Allah, and may peace and blessings be upon the Messenger of Allah. To proceed:
It is not permissible to use the expression “Allah created her and broke the mold,” because it contains a false meaning concerning Allah تعالى, in addition to being an expression for which there is no evidence. If the speaker intends that Allah تعالى became unable, after creating her, to create someone similar to her, then this is a disbelief-based belief. But if the speaker merely intends to exaggerate in describing her beauty, the expression is nevertheless false, because it constitutes speaking about Allah without knowledge and likening the manner of divine creation to the craftsmanship of created beings.
If the speaker means by saying “Allah created her and broke the mold” that after creating this person Allah تعالى was no longer able to create someone similar to them, then this meaning attributes incapacity to Allah تعالى. This is certainly false. Whoever believes that Allah تعالى is incapable of something within His power has fallen into a grave matter that contradicts the perfection of Allah’s power.
However, if the speaker does not intend this meaning and merely wishes to exaggerate in describing beauty, or means that Allah تعالى created her with a distinctive appearance unlike anyone else, this does not make the expression correct. It remains speaking about Allah تعالى without knowledge, and it is not permissible to attribute to Allah تعالى a manner or action for which there is no evidence.
Allah تعالى says:
“Say: My Lord has only forbidden immoralities—what is apparent of them and what is hidden—and sin and transgression without right, and that you associate with Allah that for which He has not sent down authority, and that you say about Allah what you do not know.” [Al-A‘raf: 33]
And He سبحانه وتعالى says:
“And do not pursue that of which you have no knowledge. Indeed, the hearing, the sight, and the heart—all of those will be questioned about.” [Al-Isra’: 36]
This expression is based on an idea resembling the work of a human craftsman: as though there were a mold in which a person was made, and then the craftsman broke it so that he could not produce another copy.
This is not a description of the manner in which Allah تعالى creates, and it is not permissible to liken the actions of Allah تعالى to the actions of created beings.
Allah عز وجل says:
“There is nothing whatsoever like Him, and He is the All-Hearing, the All-Seeing.” [Ash-Shura: 11]
Nu‘aym ibn Hammad رحمه الله said:
“Whoever likens Allah to anything from His creation has disbelieved, and whoever rejects what Allah has described Himself with has disbelieved. What Allah and His Messenger have described Him with is not anthropomorphism.”
Allah تعالى does not resemble His creation, and it is not permissible to describe the manner of His actions using concepts resembling the craftsmanship of human beings.
A Muslim does not need such an expression to emphasize the beauty or fine appearance of a person. There are clear and sound expressions that convey the intended meaning, such as:
These expressions convey admiration for beauty without attributing an unestablished meaning to Allah تعالى.
The expression “Allah created her and broke the mold” should not be used; rather, it is a false expression that should be avoided. If it is intended to mean that Allah تعالى became incapable of creating someone similar afterward, then this is a disbelief-based meaning because it attributes incapacity to Allah. If it is intended merely as an exaggeration concerning beauty, it is still an incorrect expression because it involves speaking about Allah without knowledge and likening His creation to the craftsmanship of created beings.
It is preferable to use clear and sound expressions when describing beauty, such as: “Masha’Allah, Allah created her and perfected her creation.”
And Allah knows best.
