Ruling on the fasting person breaking his fast at the adhan when there is doubt about the time

Question:
People have differed regarding breaking the fast in the city of Ta'if: some do not break their fast with the mu'adhdhin, and their argument is that some people saw the sun from al-Shifa had not yet set.
Do we break our fast with the adhan, or do we delay to verify?
And is Ta'if like al-Shifa regarding the setting of the sun?

Answer:
Every location has its own ruling. The sun sets over Ta'if before it sets over Makkah, because Ta'if is east of it. In summary, when the sun sets over the people of Ta'if, they break their fast. As for whoever is in al-Hada, or in al-Shifa, or in elevated areas, they are not permitted to break their fast until the sun sets for them, and they have their own ruling. Just as the people of Ghamid, Zahrān, the people of al-Hasa, the people of the Eastern Region, Pakistan, and others, each has his own ruling. The lands have low-lying areas and elevated areas. Those in elevated places and in the mountains break their fast when the sun sets for them, and those in the low-lying lands break their fast when the sun sets for them. It is not obligatory for them to send people to the mountains around them to look and see: has the sun set? So when the sun sets for them and for their lands in their mosques and minarets, the sun has set for them. And those elevated in the mountains have their own affair, like the people of al-Hada and their like.
