Ibn 'Umar (Allah be pleased with them) reported: Allah's Messenger, ﷺ entered the House, and Usama, Bilal and Uthman b. Talha were with him, and they kept the door closed for a considerable time. Then it was opened and I was the first to enter the House and meet Bilal, and I said: Where did Messenger of Allah ﷺ observe prayer? He said: Between these two front pillars. I, however, forgot to ask him the number of rak'ahs that he observed.

وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا يَحْيَى، وَهُوَ الْقَطَّانُ ح وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي، شَيْبَةَ حَدَّثَنَا أَبُو أُسَامَةَ، ح وَحَدَّثَنَا ابْنُ نُمَيْرٍ، - وَاللَّفْظُ لَهُ - حَدَّثَنَا عَبْدَةُ، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ دَخَلَ رَسُولُ اللَّهِ ﷺ الْبَيْتَ وَمَعَهُ أُسَامَةُ وَبِلاَلٌ وَعُثْمَانُ بْنُ طَلْحَةَ فَأَجَافُوا عَلَيْهِمُ الْبَابَ طَوِيلاً ثُمَّ فُتِحَ فَكُنْتُ أَوَّلَ مَنْ دَخَلَ فَلَقِيتُ بِلاَلاً فَقُلْتُ أَيْنَ صَلَّى رَسُولُ اللَّهِ ﷺ فَقَالَ بَيْنَ الْعَمُودَيْنِ الْمُقَدَّمَيْنِ . فَنَسِيتُ أَنْ أَسْأَلَهُ كَمْ صَلَّى رَسُولُ اللَّهِ ﷺ.
