Hadith 1115:25
Ibn Numayr narrated to us, Sayf ibn Sulayman narrated to us, he said: I heard Mujahid say: Ibn Umar was approached while he was in his house, and it was said to him: "The Prophet, may Allah bless him and grant him peace, has entered the Kaaba." He said: So I went. He said: I found the Messenger of Allah, may Allah bless him and grant him peace, had already come out, and I found Bilal standing between the two doors. I said: "O Bilal, did the Messenger of Allah, may Allah bless him and grant him peace, pray in the Kaaba?" He said: "Yes, he performed two rak'ahs between these two pillars," and he pointed to the two pillars that are to your left when you enter. He said: "Then he came out and prayed two rak'ahs facing the Kaaba."
حدثنا ابن نمير، حدثنا سيف بن سليمان، قال: سمعت مجاهدا، قال: أتي ابن عمر وهو في منزله فقيل له: إن النبي صلى الله عليه وسلم قد دخل الكعبة قال: فأقبلت، قال: فأجد رسول الله صلى الله عليه وسلم قد خرج وأجد بلالا قائما بين البابين، فقلت: يا بلال، هل صلى رسول الله صلى الله عليه وسلم في الكعبة؟ قال: " نعم ركع ركعتين بين هاتين الساريتين، وأشار له إلى الساريتين اللتين على يسارك إذا دخلت، قال: ثم خرج فصلى في وجه الكعبة ركعتين "
