Abu Shatha reported,

I set out for Hajj, and when I arrived I entered the House. When I reached the area between the two pillars, I went forward until I pressed myself against the wall. Then Ibn Umar came and prayed beside me, performing four rakahs.When he had finished, I asked, "Where in the House did the Messenger of Allah ﷺ pray?"He replied, "Usama bin Zayd told me that he prayed right here."I asked, "How many rakahs did he pray?"He said, "On this very point I find myself reproaching myself. I lived with him for a lifetime and never asked him how many rakahs he prayed."The following year I performed Hajj again, and I came and stood in that same spot. Then Ibn Zubayr came and prayed four rakahs there.

Sahih

حدثنا أبو معاوية حدثنا الأعمش عن عمارة

عن أبي الشعثاء قال

خرجت حاجا فجئت حتى دخلت البيت فلما كنت بين الساريتين مضيت حتى لزقت بالحائط فجاء ابن عمر فصلى إلى جنبي فصلى أربعا فلما صلى قلت أين صلى رسول الله ﷺ من البيت قال أخبرني أسامة بن زيد أنه صلى هاهنا فقلت كم صلى قال على هذا أجدني ألوم نفسي إني مكثت معه عمرا لم أسأله كم صلى ثم حججت من العام المقبل فجئت فقمت في مقامه فجاء ابن الزبير فصلى فيه أربعا
