Shaking hands between men and women at Workplace
In his answer to this question Dr. Monzer Kahf, Scholar in Islamic Economics & Financial Expert, who stated,
Shaking hands between men and women who are not married is not permitted. However, I heard some scholars claiming that it is Ok. I wouldn’t recommend doing it unless under necessity when avoiding it may create a problem that may be a larger sin.
But the environment you described is what every Muslim who work in the Western countries has day and night. This is the normal work environment in all these countries.
You need to be able to go through it without infringing on your Islamic values, but rather with presenting your Islamic values when appropriate. Believe me you should do a lot to enrich this environment and make it better towards righteousness and better dignity. Imagine them when they get drunk, don’t they behave without dignity? You can improve them a bit by bit provided you do not lose direction or values. With this it is permissible to stay on the full course of working environment with your colleagues.
May Allah guide all of us to what pleases Him!
