[Machine] I performed Hajj, then I went until I entered the house, and when I was between the two walls, I walked until I reached the wall. Then Ibn 'Umar came and prayed beside me, and he prayed four units. After he prayed, I asked him, "Where did the Messenger of Allah ﷺ pray in the house?" He said, "Usamah ibn Zaid informed me that he prayed here." So I asked him, "How many units did he pray?" He said, "According to what I find, I blame myself for not asking him how many units he prayed." Then I performed Hajj the following year, so I came and stood in his place, and then Ibn Zubayr came and prayed four units in it.
خَرَجْتُ حَاجًّا فَجِئْتُ حَتَّى دَخَلْتُ الْبَيْتَ فَلَمَّا كُنْتُ بَيْنَ السَّارِيَتَيْنِ مَضَيْتُ حَتَّى لَزِقْتُ بِالْحَائِطِ فَجَاءَ ابْنُ عُمَرَ فَصَلَّى إِلَى جَنْبِي فَصَلَّى أَرْبَعًا فَلَمَّا صَلَّى قُلْتُ لَهُ أَيْنَ صَلَّى رَسُولُ اللهِ ﷺ مِنَ الْبَيْتِ؟ قَالَ أَخْبَرَنِي أُسَامَةُ بْنُ زَيْدٍ أَنَّهُ صَلَّى هَاهُنَا فَقُلْتُ كَمْ صَلَّى؟ قَالَ عَلَى هَذَا أَجِدُنِي أَلُومُ نَفْسِي إِنِّي مَكَثْتُ مَعَهُ عُمُرًا لَمْ أَسْأَلْهُ كَمْ صَلَّى ثُمَّ حَجَجْتُ مِنَ الْعَامِ الْمُقْبِلِ فَجِئْتُ فَقُمْتُ فِي مَقَامِهِ فَجَاءَ ابْنُ الزُّبَيْرِ فَصَلَّى فِيهِأَرْبَعًا
