Masjid Quba is the first mosque built in Islam and the first mosque in the city of Madinah. Allah revealed this verse about it:
"A mosque founded upon piety from the first day is more deserving that you stand therein. In it are men who love to purify themselves, and Allah loves those who purify themselves." (Surah At-Tawbah, 9:108)

It is one of the largest mosques in Madinah after the Prophet’s Mosque. It is located south of Madinah and was built by the Prophet Muhammad (peace be upon him) after he migrated from Makkah to Madinah.

The Prophet said: "Whoever performs ablution (wudu) at home and then prays in Masjid Quba will get the reward of Umrah." The Prophet visited Masjid Quba every Saturday, either walking or riding.

Muslims have kept the mosque safe and expanded it over time. The biggest expansion happened during the rule of King Salman bin Abdulaziz Al Saud. On April 8, 2022 (7 Ramadan 1443 AH), Crown Prince Mohammed bin Salman announced a new project to expand the mosque and its surroundings. The project will increase the mosque’s capacity to hold 66,000 worshippers and cover 50,000 square meters.
