You must follow the Muslim ruler if you have one or the Islamic authority in your country!

If you don’t have neither one, you should follow the sighting.

in my country,people are always divided into 2 when it comes during eid moon sighting..Half follow the saudi sighting and half follow the local sighting..However my question is regarding fasting on the day of arafa..We from Africa,should we follow our sighting and fast on the 9th or we have to follow those in makkah and fast on the date they will be in arafa?Note that datewise,saudis are ahead of us by 1 day..
