Question :
What should someone do if they fasted for 30 days in their country, then traveled to a place where people are still fasting?
The Answer :
If a person completes 30 days of fasting in their country and then travels to another country where people are still fasting, they should continue fasting with them until they observe Eid. Even if they have already completed 30 days, he/she should abstain from eating and drinking and join the people of that country because he/she has now become part of that community.
