Someone came to Ibn ʿUmar and said, "Here is Messenger of Allah ﷺ entering the Kaʿba." Ibn ʿUmar said, "I went there but the Prophet ﷺ had come out of the Kaʿba and I found Bilal standing between its two doors. I asked Bilal, 'Did the Prophet ﷺ pray in the Kaʿba?' Bilal replied, 'Yes, he prayed two rakʿat between the two pillars which are to your left on entering the Kaʿba. Then Messenger of Allah ﷺ came out and offered a two-rakʿat prayer facing the Kaʿba.' "  

أُتِيَ ابْنُ عُمَرَ فَقِيلَ لَهُ هَذَا رَسُولُ اللَّهِ ﷺ دَخَلَ الْكَعْبَةَ فَقَالَ ابْنُ عُمَرَ فَأَقْبَلْتُ وَالنَّبِيُّ ﷺ قَدْ خَرَجَ وَأَجِدُ بِلاَلاً قَائِمًا بَيْنَ الْبَابَيْنِ فَسَأَلْتُ بِلاَلاً فَقُلْتُ أَصَلَّى النَّبِيُّ ﷺ فِي الْكَعْبَةِ قَالَ نَعَمْ رَكْعَتَيْنِ بَيْنَ السَّارِيَتَيْنِ اللَّتَيْنِ عَلَى يَسَارِهِ إِذَا دَخَلْتَ ثُمَّ خَرَجَ فَصَلَّى فِي وَجْهِ الْكَعْبَةِ رَكْعَتَيْنِ  

Somebody came to the house of Ibn ʿUmar and told him that Messenger of Allah ﷺs had entered the Kaʿba. Ibn ʿUmar said, "I went in front of the Kaʿba and found that Messenger of Allah ﷺ had come out of the Kaʿba and I saw Bilal standing by the side of the gate of the Kaʿba. I said, 'O Bilal! Has Allah's Apostle ﷺ prayed inside the Kaʿba?' Bilal replied in the affirmative. I said, 'Where (did he pray)?' He replied, '(He prayed) Between these two pillars and then he came out and offered a two rakʿat prayer in front of the Kaʿba.' " Abu ʿAbdullah said: Abu Huraira said, "The Prophet ﷺ advised me to offer two rakʿat of Duha prayer (prayer to be offered after sunrise and before midday). " Itban (bin Malik) said, "Messenger of Allah ﷺ and Abu Bakr, came to me after sunrise and we aligned behind the Prophet ﷺ and offered two rakʿat."  

سَمِعْتُ مُجَاهِدًا يَقُولُ أُتِيَ ابْنُ عُمَرَ ؓ فِي مَنْزِلِهِ فَقِيلَ لَهُ هَذَا رَسُولُ اللَّهِ ﷺ قَدْ دَخَلَ الْكَعْبَةَ قَالَ فَأَقْبَلْتُ فَأَجِدُ رَسُولَ اللَّهِ ﷺ قَدْ خَرَجَ وَأَجِدُ بِلاَلاً عِنْدَ الْبَابِ قَائِمًا فَقُلْتُ يَا بِلاَلُ صَلَّى رَسُولُ اللَّهِ ﷺ فِي الْكَعْبَةِ قَالَ نَعَمْ قُلْتُ فَأَيْنَ قَالَ بَيْنَ هَاتَيْنِ الأُسْطُوَانَتَيْنِ ثُمَّ خَرَجَ فَصَلَّى رَكْعَتَيْنِ فِي وَجْهِ الْكَعْبَةِ قَالَ أَبُو عَبْدِ اللَّهِ قَالَ أَبُو هُرَيْرَةَ ؓ أَوْصَانِي النَّبِيُّ ﷺ بِرَكْعَتَىِ الضُّحَى وَقَالَ عِتْبَانُ غَدَا عَلَىَّ رَسُولُ اللَّهِ ﷺ وَأَبُو بَكْرٍ ؓ بَعْدَ مَا امْتَدَّ النَّهَارُ وَصَفَفْنَا وَرَاءَهُ فَرَكَعَ رَكْعَتَيْنِ  

[Machine] Ibn Umar was at his house when someone told him that the Prophet ﷺ had entered the Kaaba. So, he approached and found the Messenger of Allah ﷺ had come out, and he found Bilal standing between the two doors. Ibn Umar asked Bilal, "Did the Messenger of Allah ﷺ pray in the Kaaba?" Bilal replied, "Yes, he prayed two units of prayer between these two pillars," and he pointed to the two pillars to the left when you enter. Then the Prophet ﷺ came out and prayed two units of prayer facing the Kaaba.  

أُتِيَ ابْنُ عُمَرَ وَهُوَ فِي مَنْزِلِهِ فَقِيلَ لَهُ إِنَّ النَّبِيَّ ﷺ قَدْ دَخَلَ الْكَعْبَةَ قَالَ فَأَقْبَلْتُ قَالَ فَأَجِدُ رَسُولَ اللهِ ﷺ قَدْ خَرَجَ وَأَجِدُ بِلَالًا قَائِمًا بَيْنَ الْبَابَيْنِ فَقُلْتُ يَا بِلَالُ هَلْ صَلَّى رَسُولُ اللهِ ﷺ فِي الْكَعْبَةِ؟ قَالَ نَعَمْ رَكَعَ رَكْعَتَيْنِ بَيْنَ هَاتَيْنِ السَّارِيَتَيْنِ وَأَشَارَ لَهُ إِلَى السَّارِيَتَيْنِ اللَّتَيْنِ عَلَى يَسَارِكِ إِذَا دَخَلْتَ قَالَ ثُمَّخَرَجَ فَصَلَّى فِي وَجْهِ الْكَعْبَةِ رَكْعَتَيْنِ  

The Messenger of Allah has entered the Kabah." So Ibn Umar said, I (Ibn Umar) came and found that the Messenger of Allah had come out, and I found Bilal standing at the door. I said: "O Bilal, did the Messenger of Allah pray inside the Kabah?' He said: "Ues." I said: "Where>" He said: "Between these two columns, two Rakahs. Then he came out and prayed two Rakahs in front of the Kabah." (Using translation from Nasāʾī 2908)  

سَمِعْتُ مُجَاهِدًا يَقُولُ أَذِنَ ابْنُ عُمَرَ فِي مَنْزِلِهِ فَقِيلَ هَذَا رَسُولُ اللهِ ﷺ قَدْ دَخَلَ الْكَعْبَةَ قَالَ فَأَقْبَلْتُ فَأَجِدُ رَسُولَ اللهِ ﷺ قَدْ خَرَجَ وَأَجِدُ بِلَالًا عَلَى الْبَابِ قَائِمًا فَقُلْتُ يَا بِلَالُ صَلَّى رَسُولُ اللهِ ﷺ فِي الْكَعْبَةِ؟ قَالَ نَعَمْ قُلْتُ أَيْنَ؟ قَالَ «مَا بَيْنَ هَاتَيْنِ الْأُسْطُوَانَتَيْنِ رَكْعَتَيْنِ ثُمَّ خَرَجَ فَصَلَّى رَكْعَتَيْنِ فِي وَجْهِ الْكَعْبَةِ»
