MASJID AL QIBLATAYN
It is clear from the name of this mosque that there is a connection between it and the Muslims’ direction of prayer called as Qiblah in Arabic.
It is located in the south west near the valley of Al-‘Aqeeq and above slightly high land. It is about five kilometers away from the mosque of the Prophet in the north-west. It has undergone renovation many times. The latest in the series of extension and renovation projects was carried out by the Bin Laden company. The mosque now has two floors: the first floor is allocated for administering the affairs of the mosque and the second floor for prayer. It is 1190 square meters. A 400 square meter balcony is specified for women, overlooking the praying area for men. There is a place for teaching the Quran. Next to the mosque, a tree lined internal yard has been added.
At first, the Muslims prayed facing towards the direction of Bayt Al-Maqdis (Jerusalem), then, praying towards Jerusalem was abrogated by the Divine order to pray towards Al-Masjid Al-Haraam when Allaah The Almighty revealed: We have certainly seen the turning of your face, [O Muhammad], toward the heaven, and We will surely turn you to a Qiblah with which you will be pleased. So turn your face toward Al-Masjid Al-Haraam. And wherever you [believers] are, turn your faces toward it [in prayer]. Indeed, those who have been given the Book know well that it is the truth from their Lord. And Allaah is not unaware of what they do.Quran Surah Baqrah 2:144
Change Of Qibla From Bait-ul-maqdis to Ka'ba was narrated in the following hadith. Anas(R) reported:The Messenger of Allah (ﷺ) used to pray towards Bait-ul-Maqdis, that it was revealed (to him):" Indeed We see the turning of the face to heaven, wherefore We shall assuredly cause thee to turn towards Qibla which shall please thee. So turn thy face towards the sacred Mosque (Ka'ba)" (Quran 2. 144). A person from Banu Salama was going; (he found the people) in ruk'u (while) praying the dawn prayer and they had said one rak'ah. He said in a loud voice: Listen! the Qibla has been changed and they turned towards (the new) Qibla (Ka'ba) in that very state. Sahih Muslim 527 
In another narration reported from the Prophet (ﷺ): He used to say when he visited Al-Baqi‘: May Allah have mercy on those who have gone ahead of us and those who will come later on. O, Allah forgive the people of Baqi‘ Al-Gharqad, Sahih Muslim 974. It is also prescribed for those who visit Al-Masjid Al-Nabawy to visit the Masjid of Quba' Quba' (a town near Madinah where the Prophet established the first mosque) and offer two Rak‘ahs there, because the Prophet (ﷺ) used to visit it and offer two Rak‘ahs there on Saturdays, Sahih al-Bukhari Vol.2: 1191. He (peace be upon him) said: If a person purifies themselves at home then goes to Masjid Quba' to offer Salah, they will receive a reward equal to that of performing ‘Umrah (lesser pilgrimage).These are the places that should be visited in Al-Madinah Al-Munawwarah. However, regarding the Seven Masjids, Al-Qiblatayn Masjid (The Mosque of the Two Qiblahs) and other places mentioned by some people as necessary to visit, this is groundless and there is no evidence on it. A Mu’min should always follow and imitate, not innovate something new in religion. May Allah grant us success!
