We often read about and hear the common people and their writers and poets describing nurses as “angels of mercy.” Is this permissible?
It is not permissible to apply this description to nurses, because the angels are male and are not female. Allah denounced the mushrikeen (pagans) for describing the angels as female. Moreover, the angels of mercy have their own description which cannot be applied to nurses, for there are good and bad nurses, so it is not permissible to apply this description to them.
And Allah knows best.
