Sahih Muslim 1329e
وَحَدَّثَنِي حُمَيْدُ بْنُ مَسْعَدَةَ، حَدَّثَنَا خَالِدٌ، - يَعْنِي ابْنَ الْحَارِثِ - حَدَّثَنَا عَبْدُ اللَّهِ، بْنُ عَوْنٍ عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ انْتَهَى إِلَى الْكَعْبَةِ وَقَدْ دَخَلَهَا النَّبِيُّ صلى الله عليه وسلم وَبِلاَلٌ وَأُسَامَةُ وَأَجَافَ عَلَيْهِمْ عُثْمَانُ بْنُ طَلْحَةَ الْبَابَ قَالَ فَمَكَثُوا فِيهِ مَلِيًّا ثُمَّ فُتِحَ الْبَابُ فَخَرَجَ النَّبِيُّ صلى الله عليه وسلم وَرَقِيتُ الدَّرَجَةَ فَدَخَلْتُ الْبَيْتَ فَقُلْتُ أَيْنَ صَلَّى النَّبِيُّ صلى الله عليه وسلم قَالُوا هَا هُنَا . قَالَ وَنَسِيتُ أَنْ أَسْأَلَهُمْ كَمْ صَلَّى.
Abdullah ibn Umar reported that he arrived at the Kaaba while the Prophet, Bilal, and Usama had entered it, and Uthman ibn Talha had closed the door behind them. They stayed inside for some time. Then the door was opened, the Prophet came out, and I climbed the steps and entered the House. I asked, Where did the Prophet pray? They said, Right here. I forgot to ask them how many units of prayer he performed.
