You can’t be alone with one man. If two men or more are there, this is permissible. If a man enters when you are alone, leave the lift and wait for an empty one.

I live in a country where most of the buildings in the country are high rise, it is impossible for me to take the staircase to climb upto 19th floor. Sometimes when I take the lift, some non mahram also enter the lift. … …Sometimes I will be the only female and 2 to 3 men in the lift. I try my level best to avoid such situations. But some times I cannot. So what should do in such situations? Am I forgiven in such circumstances?
