Is it permissible for a government employee to exploit raw materials available from projects for personal use under the pretext of a low salary?

It is not permissible for an employee to exploit their position or use government work tools for personal gain, unless the use is minimal, does not harm the tools, and is customary or authorized by the responsible authorities. For he is entrusted with what is under his hand, and he has agreed to the stipulated salary, and a low salary does not justify consuming public property.
