حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ ثَابِتٍ، وَحُمَيْدٍ، عَنْ أَنَسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم وَأَصْحَابَهُ كَانُوا يُصَلُّونَ نَحْوَ بَيْتِ الْمَقْدِسِ فَلَمَّا نَزَلَتْ هَذِهِ الآيَةُ ‏{‏ فَوَلِّ وَجْهَكَ شَطْرَ الْمَسْجِدِ الْحَرَامِ وَحَيْثُ مَا كُنْتُمْ فَوَلُّوا وُجُوهَكُمْ شَطْرَهُ ‏}‏ فَمَرَّ رَجُلٌ مِنْ بَنِي سَلِمَةَ فَنَادَاهُمْ وَهُمْ رُكُوعٌ فِي صَلاَةِ الْفَجْرِ نَحْوَ بَيْتِ الْمَقْدِسِ أَلاَ إِنَّ الْقِبْلَةَ قَدْ حُوِّلَتْ إِلَى الْكَعْبَةِ مَرَّتَيْنِ فَمَالُوا كَمَا هُمْ رُكُوعٌ إِلَى الْكَعْبَةِ ‏.‏

Anas said:The Prophet (ﷺ) and his Companions used to pray in the direction of Jerusalem. When the following verse was revealed: " So turn thy face towards the inviolable mosque"; and Ye (O Muslims), wheresoever ye may be, turn your face towards it"(ii. 144), a man passed by the people of Banu Salamah.

So they turned their faces towards the Ka'bah while they were bowing
