Jamil and Salma both have the same charge. 

Jamil and Salma are insulated from the ground, so the electric charge has nowhere to go.  Since the two are in contact, the charge, once accumulated, would spread evenly between them, seeking equilibrium. 

If any difference in charge existed, then that would result in the presence of voltage, and that would require a current to form.  Because the electricity is static, and there is nowhere for it to go, this is contrary to electrical physics.  The difference would quickly equalize in one spark (i.e. lightning).
