Masjid Quba
Masjid Quba is the first mosque built in Islam. The Prophet Muhammad ﷺ stopped at Quba, then a settlement on the southern edge of Madinah, when he arrived from Makkah on the hijrah, and laid its foundations himself before continuing into the city. The Qur'an refers to it in Surah at-Tawbah as a mosque founded upon piety from the first day. The building has been rebuilt and enlarged many times since, most recently into the large white mosque you see today, with broad courtyards and space for thousands of worshippers.
Quba is the busiest of the Madinah sites and the one most pilgrims want to pray in, so allow longer here than anywhere else on the route — thirty to forty minutes at least, and more on a Saturday morning, when it is at its fullest. There are prayer halls and facilities for both men and women. Your driver will wait in the car park.
