Masjid al-Qiblatain

Masjid al-Qiblatain (المسجد القبلتین) (Mosque of the two Qiblas) is a mosque in Medina that is historically important for Muslims as the place where the Islamic prophet Muhammad, leading the prayer, is said to have been commanded to change the direction of prayer (qibla) from Jerusalem to Mecca. Thus it uniquely contained two prayer niches (mihrabs). Recently the mosque was renovated; the old prayer niche facing Jerusalem was removed, and the one facing Mecca was left.
