What is the ruling on using medicine to increase height, and does it constitute an objection to Allah's decree?

It is permissible to use medication to increase growth hormone for someone who is of weak build or noticeably short in stature, because this is considered a form of treatment for hormone deficiency, and not an alteration of Allah's creation. A condition for treating with this hormone is to ensure its safety and freedom from harm, based on the hadith (definition): "There should be no harm or reciprocating harm." Therefore, a specialist physician must be consulted.
