Placing One's Face and Chest On The Back Wall Of The Kabah
أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ، قَالَ حَدَّثَنَا خَالِدٌ، عَنْ عَبْدِ الْمَلِكِ، عَنْ عَطَاءٍ، عَنْ أُسَامَةَ، قَالَ خَرَجَ رَسُولُ اللَّهِ صلى الله عليه وسلم مِنَ الْبَيْتِ صَلَّى رَكْعَتَيْنِ فِي قُبُلِ الْكَعْبَةِ ثُمَّ قَالَ هَذِهِ الْقِبْلَةُ .
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.'"
