Al Qiblatayn Mosque
The Masjid Al-Qiblatain is another mosque also historically important to Muslims as one of the three oldest mosques along with those of Nabwiyah and Quba. It is supposed to have been built in 623 CE / 1 H meaning during the first year of the Islamic calendar.
According to Muslim belief the Masjid Al-Qiblatain is where the command was sent to Muhammad to change the direction of prayer (qibla) from Jerusalem to Mekkah according to authentic Hadith. Thus it was the only mosque containing two prayer niches (mihrab) but the one oriented towards Jerusalem was recently removed.
