Narrated Al-Bara:
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى ، حَدَّثَنَا يَحْيَى ، عَنْ سُفْيَانَ ، حَدَّثَنِي أَبُو إِسْحَاقَ ، قَالَ سَمِعْتُ الْبَرَاءَ ـ رضى الله عنه ـ قَالَ صَلَّيْنَا مَعَ النَّبِيِّ صلى الله عليه وسلم نَحْوَ بَيْتِ الْمَقْدِسِ سِتَّةَ عَشَرَ ـ أَوْ سَبْعَةَ عَشَرَ ـ شَهْرًا، ثُمَّ صَرَفَهُ نَحْوَ الْقِبْلَةِ.
We prayed along with the Prophet (ﷺ) 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)
