حَدَّثَنَا يَحْيَى عَنْ عُبَيْدِ اللَّهِ حَدَّثَنِي نَافِعٌ عَنْ عَبْدِ اللَّهِ قَالَ دَخَلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْبَيْتَ هُوَ وَبِلَالٌ وَأُسَامَةُ بْنُ زَيْدٍ وَعُثْمَانُ بْنُ طَلْحَةَ فَأَجَافُوا الْبَابَ وَمَكَثُوا سَاعَةً ثُمَّ خَرَجَ فَلَمَّا فُتِحَ كُنْتُ أَوَّلَ مَنْ دَخَلَ فَسَأَلْتُ بِلَالًا أَيْنَ صَلَّى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ بَيْنَ الْعَمُودَيْنِ الْمُقَدَّمَيْنِ وَنَسِيتُ أَنْ أَسْأَلَهُ كَمْ صَلَّى
مسند امام احمد بن حنبل · Hadith 5176
It was narrated that 'Abdullah said: The Messenger of Allah (PBUH) entered the House (the Ka'bah) along with Bilaal, Usaatnah ibn Zayd and Uthmaan ibn Talhah, then they closed the door. They stayed inside for a while, then he came out. When it was opened, I was the first one to in and I asked Bilaal: Where did the Messenger of Allah (PBUH) pray? He said between the two front pillars. And I forgot to ask him how many (rak'ahs) he prayed.
