Correcting city prayer times
If a city page shows a timing issue, open that city page and use the prayer-time correction option there. That keeps the correction attached to the exact city instead of sending a vague general message.
This is the best path when the issue is related to the city, country, calculation method, or local time zone.
Adding or updating a mosque
To add a mosque, go to the correct city page first and use the add-mosque option. To update a mosque name, details, or iqama information, open the mosque page itself and use the update form there.
That helps keep updates linked to the right city and mosque and reduces duplicates or misplaced entries.
If you cannot find the right page
Start with the site search and look for the city, country, or mosque name. Once you open the correct page, the relevant correction or update form will be available there.
This is faster and more accurate than a generic contact request because the update starts in the correct context.
