Question

Where was the first mosque built and what is its importance?

Answer 1

Quba — the first mosque in the history of Islam. Quba Mosque to the south of Madinah is the second largest and prestigious mosque in the city after the Prophet's Mosque, but claims the first place owing to its importance in Islamic history having been built in the first year of the Islamic calendar.

Answer 2

Explanation:

In this case, either the Mosque of the Companions in the Eritrean city of Massawa, or the Quba Mosque in the Hejazi city of Medina (the first structure built by Muhammad upon his emigration from Mecca in 622 CE), would be the first mosque that was built in the history of Islam.
