‘Founded on piety and devoutness' Masjid Al-Quba in the outlying environs of Madina is the oldest mosque in the world. Prophet Muhammad (pbuh) spent more than 20 nights in this mosque (after migrating from Makkah) praying qasr (a short prayer). It is mentioned in the Qur'an as the mosque founded on piety and devoutness (Masjid Al-Taqwa). n Prophet Muhammad (pbuh) used to go there, riding or on foot, every Saturday and offer a two rak'ah prayer. He advised others to do the same, saying, “Whoever makes ablutions at home and then goes and prays in the Mosque of Quba, he will have a reward like that of an Umrah. This hadith is reported by Ahmad ibn Hanbal, Al-Nasa'i, Ibn Majah and Hakim Al-Nishaburi. When Quba Mosque was rebuilt in 1986, the Madina architecture was retained - ribbed white domes, and basalt facing and modest exterior - qualities that recalls Madina's simplicity. The courtyard, is flagged with black, red and white marble. It is screened overhead by day from the scorching heat with shades. Arabesque latticework filters the light of the palm groves outside. The merits of Masjid Quba are mentioned in 19 Sahih Al-Bukhari hadiths, 13 Sahih Muslim hadiths, two Sunan Abu Dawood hadiths, and six Al-Muwatta hadiths.
