Ibn ʿUmar said, "The Prophet ﷺ arrived at Mecca and sent for ʿUthman bin Talha. He opened the gate of the Kaʿba and the Prophet, Bilal, Usama bin Zaid and ʿUthman bin Talha entered the Kaʿba and then they closed its door (from inside). They stayed there for an hour, and then came out." Ibn ʿUmar added, "I quickly went to Bilal and asked him (whether the Prophet ﷺ had prayed). Bilal replied, 'He prayed in it.' I asked, 'Where?' He replied, 'Between the two pillars.' "Ibn ʿUmar added, "I forgot to ask how many rakʿat he (the Prophet) had prayed in the Kaʿba."  

أَنَّ النَّبِيَّ ﷺ قَدِمَ مَكَّةَ فَدَعَا عُثْمَانَ بْنَ طَلْحَةَ فَفَتَحَ الْبَابَ فَدَخَلَ النَّبِيُّ ﷺ وَبِلاَلٌ وَأُسَامَةُ بْنُ زَيْدٍ وَعُثْمَانُ بْنُ طَلْحَةَ ثُمَّ أُغْلِقَ الْبَابُ فَلَبِثَ فِيهِ سَاعَةً ثُمَّ خَرَجُوا قَالَ ابْنُ عُمَرَ فَبَدَرْتُ فَسَأَلْتُ بِلاَلاً فَقَالَ صَلَّى فِيهِ فَقُلْتُ فِي أَىٍّ قَالَ بَيْنَ الأُسْطُوَانَتَيْنِ قَالَ ابْنُ عُمَرَ فَذَهَبَ عَلَىَّ أَنْ أَسْأَلَهُ كَمْ صَلَّى
