Sunan Abi Dawud, Hadith 1897

‘Abd Allaah bin Abi Aufa said the Apostle of Allaah performed ‘Umrah and went round the House(the Ka’bah) and prayed behind the station (Maqam Ibrahim) two rak’ahs and he was accompanied by so many people that he was hidden by them. ‘Abd Allaah bin Abi Aufa was asked Did the Apostle of Allaah enter the Ka’bah ? He replied “No”.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا خَالِدُ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ أَبِي خَالِدٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي أَوْفَى، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم اعْتَمَرَ فَطَافَ بِالْبَيْتِ وَصَلَّى خَلْفَ الْمَقَامِ رَكْعَتَيْنِ وَمَعَهُ مَنْ يَسْتُرُهُ مِنَ النَّاسِ فَقِيلَ لِعَبْدِ اللَّهِ أَدَخَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم الْكَعْبَةَ قَالَ لاَ ‏.‏
