Non Muslim working in Madina... Urgent

Hello,
I am an engineer working in Riyadh  now.
But since my beginning many times our company general manager asked me ... Am I ready to work in Madina ?
Same number of times I replied ... I have no problem to work anywhere but I am Hindu... As per saudi law I am not allowed to enter in Madina

He was not forcing upto last week.

But since last week he is asking me ... I must go there.
Today finalise ... I am leaving by tomorrow.

He also saying company will take care if any problem raises.

Buy myself scared... But due to my commitments at home I can't quit the job.

So what is the best corse of action?

If I become must going...what kind of things (papers) I need to carry to protect myself?

Please advice ...urgent

Dear,

You are an educated gentleman and aware of Saudi Laws as well. You must abide by the law of the land. No one comes to help in this world.

Please beware as Mecca and Medina are sacred places . It's  not all right for your employer to say that they'll take care of things if a problem should arise, and  should know better. However Just be careful because if anyone finds out and informs on you, you could get thrown out of Saudi completely and then what would happen to your home commitments then my friend. :(
