My name is Siddikur Rahman and I am writing from United States of America. If we follow local moon sighting, do we fast on 9th Dhul Hijjah in USA or do we fast on actual Arafah day in Saudi Arabia (regardless whether it's 8th or 9th Dhul Hijjah in USA). For instance, this year, the actual day of Arafah (in Saudi Arabia) was October 3rd (9th Dhul Hijjah), but at the same day in USA was (8th Dhul Hijjah), and the 9th Dhul Hijjah was October 4th in USA (based on local moon sighting).
بسم الله الرحمن الرحيم
If you are in America then you should keep fast on 9th Dhul Hijjah as per the moon sighting of your area not as per the moon sighting of Saudi Arabia.
Allah knows Best!
