1 Question: I am working in a company and supposed to shake hands with customers, male or female. If don't do that, it would be considered impolite and there is a risk of losing my job and suffering the aftermath? What should I do?
Answer: A Muslim man is not allowed to shake hands with a woman without a barrier, such as gloves, unless refraining from shaking hands will put him in a considerable harm or unbearable difficulty. In the latter case, he is allowed to shake hands to the extent of necessity only.sistani.org/15243
