Arrival at Quba and Building of Quba Mosque

After the eight-day journey from Mecca, the Prophet ﷺ arrived at Quba on the outskirts of Medina. He stayed with Kulthum ibn al-Hidm for about four days and established Masjid Quba, the first mosque built in Islam. The Quran refers to it as 'a mosque founded on righteousness from the first day' (9:108). The Prophet later said that praying two rak'ahs in Masjid Quba equals the reward of an Umrah.
