It was narrated that Usmah said:

"The Messenger of Allah came out of the House and prayed two Rakahs in front of the Kabah, then he said: 'This is the Qiblah.'"

أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ، قَالَ حَدَّثَنَا خَالِدٌ، عَنْ عَبْدِ الْمَلِكِ، عَنْ عَطَاءٍ، عَنْ أُسَامَةَ، قَالَ خَرَجَ رَسُولُ اللَّهِ ﷺ مِنَ الْبَيْتِ صَلَّى رَكْعَتَيْنِ فِي قُبُلِ الْكَعْبَةِ ثُمَّ قَالَ " هَذِهِ الْقِبْلَةُ " .
