Resigning during probation period and travel back to home country

Good day Sir,

I am in KSA for the past 2 months and I'm not interested in working with my company as a barista anymore, because my manager is not good and always scolds us and says that he will deduct my salary for silly issues.

I'm feeling insecure to work here. Though I'm in a probation period can I resign my job and go back to my home?

Will my company charge me anything for resigning?
