Is supplicating for increased height considered an excess in supplication? And is changing jawlines through exercise, rather than surgery, considered altering God's creation?

If a person has passed the growth stage during which a man's height typically stops increasing (up to the early twenties), then supplicating for increased height is considered an تجاوز (transgression) and a lack of proper etiquette with Allah. This is because it involves asking for something contrary to His established sunnah in creation, and the Prophet, peace and blessings be upon him, condemned transgression in supplication. As for accentuating jawlines through exercises, there is no harm in it, provided that it is not done through surgery or filler injections, as these are not permissible except for treating a disfigurement.
