Male nurse being alone with female nurse in the hospital

It is not permissible for those in charge of hospitals to put a male
nurse and a female nurse on duty overnight on their own to keep a watch
on the patients. This is wrong and is a great evil, and it is a call
to evil actions.  If this man is alone with this woman in one place,
they are not safe from the possibility that the Shaytaan may make immoral
actions and the things that lead to such actions attractive to them.
It was reported in a saheeh hadeeth that the Messenger of Allaah
(peace and blessings of Allaah be upon him) said: “No man is alone with
a (non-mahram) woman but the Shaytaan is the third one present.” So
this work is not permissible and you have to leave it, because it may
lead to that which Allaah has forbidden. Allaah will compensate you
with something better if you leave it for the sake of Allaah. Allaah
says (interpretation of the meaning):

“And whosoever fears Allaah and keeps his duty to Him, He will
make a way for him to get out (from every difficulty).

And He will provide him from (sources) he never could imagine”
[al-Talaaq 65:2-3]

“and whosoever fears Allaah
and keeps his duty to Him, He will make his matter easy for him” [al-Talaaq
65:4]  

The female nurse also has to be cautious and resign if she cannot
achieve what she wants, because both of you are responsible with regard
to what Allaah has enjoined and forbidden.
