Inshallah-God willing is a very frequently used term among Muslims. It stands for "if God wills, it will happen" and its meant to be a positive thing. If someone is asked to do something and then replies "inshallah" it should be like a promise to do ones best and only if God wills otherwise they won't be able to deliver the promise.
Nevertheless inshallah has become widely used to portray something else, like a promise to not do something. In the working environments in KSA where multiple nationalities and cultures mix, inshallah has caught on a negative sound to it. The saying is used and abused by expats and Saudis as well.
For example in the hospital culture inshallah is commonly used to brush things off as unimportant or insignificant. When there are no intentions to actually perform a task inshallah might be said to give false hopes. Or when someone does not take another person too seriously or is just too busy, inshallah comes in "handy" to take the responsibility off oneself. Simply not knowing the answer to something might be an inshallah.
Inshallah has been abused to the point it has become unfavorable and triggers bad feelings among co-workers.
For instance a physician replying "inshallah" after being asked to order a medication or to come see a patient on the ward will signal to the nurse that most likely the dr. will need to be reminded few times before this actually occurs.
The patients sometimes get upset and refuse to accept an "inshallah" from the doctors as an answer because they know it is like a false promise or a delay in treatment.
Nurses at times say to the patients "inshallah" rather than "I'm sorry" when they are too busy to perform a certain task.
Pharmacists might use inshallah when asked for the amount of time needed for a medication to be ready.
A ward clerk might opt to say "inshallah" in response to calm down and get rid of demanding relatives asking too many questions.
When discussing diagnosis or prognosis with patients some physicians rather say "inshallah" then reveal the truth of the matter.
And the list goes on unfortunately..It's as if the whole term has been turned upside down from its real meaning.
