Geez

rafāˀi - reparator, restitutor (medicus) (repairer, restorer, doctor) (LLA 320)

The meaning “to cure, to heal” is only sporadically attested in Geez, whereas the normal meaning of rafˀa is “to sew, to mend,” which is also common for rfˀ in Arabic

*rpˀ - to heal, to protect (Kogan 2015: 121)
An ultimate connection with *rpy ‘to relax’ is not to be excluded
