"The Messenger of Allah entered the Kabah and recited the Tasbih and the Takbir in its corners, but he did not pray. Then he came out and prayed two Rakahs behind the Maqam, then he said: 'This is Qiblah.'" (Using translation from Nasāʾī 2909)
دَخَلَ رَسُولُ اللهِ ﷺ الْكَعْبَةَ فَسَبَّحَ فِي نَوَاحِيهَا وَكَبَّرَ وَلَمْ يُصَلِّ ثُمَّ خَرَجَ فَصَلَّى خَلْفَ الْمَقَامِ رَكْعَتَيْنِ ثُمَّ قَالَ «هَذِهِ الْقِبْلَةُ»
