Narrated Al-Bara: We prayed along with the Prophet facing Jerusalem for sixteen or seventeen months. Then Allah ordered him to turn his face towards the Qibla (in Mecca):-- "And from whence-so-ever you start forth (for prayers) turn your face in the direction of (the Sacred Mosque of Mecca) Al-Masjid-ul Haram.." (2.149)
