It was narrated that Ibn ‘Umar said:
“The Messenger of Allah ﷺ entered the Ka’bah on the Day of the Conquest (of Makkah), with Bilal and ‘Uthman bin Shaibah, and they locked the door behind them from the inside. When they came out, I asked Bilal: ‘Where did the Messenger of Allah ﷺ pray?’ He told me that when he entered, he turned to his right and prayed in the direction that he was facing, between the two columns.”

حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ إِبْرَاهِيمَ الدِّمَشْقِيُّ، حَدَّثَنَا عُمَرُ بْنُ عَبْدِ الْوَاحِدِ، عَنِ الأَوْزَاعِيِّ، حَدَّثَنِي حَسَّانُ بْنُ عَطِيَّةَ، حَدَّثَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، قَالَ دَخَلَ رَسُولُ اللَّهِ ﷺ يَوْمَ الْفَتْحِ الْكَعْبَةَ وَمَعَهُ بِلاَلٌ وَعُثْمَانُ بْنُ شَيْبَةَ فَأَغْلَقُوهَا عَلَيْهِمْ مِنْ دَاخِلٍ فَلَمَّا خَرَجُوا سَأَلْتُ بِلاَلاً أَيْنَ صَلَّى رَسُولُ اللَّهِ ﷺ فَأَخْبَرَنِي أَنَّهُ صَلَّى عَلَى وَجْهِهِ حِينَ دَخَلَ بَيْنَ الْعَمُودَيْنِ عَنْ يَمِينِهِ ثُمَّ لُمْتُ نَفْسِي أَنْ لاَ أَكُونَ سَأَلْتُهُ كَمْ صَلَّى رَسُولُ اللَّهِ ﷺ .
