Why is it not permissible to supplicate for extreme beauty, and is that considered an transgression in supplication, and is it a miracle?

Allah the Almighty is All-Capable, and believing in this is fundamental to the believer's creed. However, it is not permissible to supplicate for something that contradicts Allah's sunnah (way/pattern) in His creation, because that constitutes an transgression in supplication. Allah does not do what contradicts His cosmic sunnah, such as a person asking for immortality, or the removal of human necessities, or knowledge of the unseen, or for Allah to grant him a child without a wife. Allah's sunnah in His creation has been established on not altering the human form. So, praise Allah for what He has apportioned for you and strive to draw closer to Him.
