Abu Shatha reported,

He set out for Hajj and entered the House. When he reached the two pillars, he proceeded until he was pressed against the wall.He said, Ibn Umar then came and stood beside me and prayed four units.When he had finished praying, I asked him, "Where did the Messenger of Allah ﷺ pray inside the House?"He replied, "Right here. Usama bin Zayd informed me that he prayed here."I asked, "How many units did he pray?"He said, "It is for this very reason that I find myself blaming myself, that I spent a lifetime in his company yet did not ask him how many units he prayed."The following year, he said, I went out for Hajj again and came and stood at the same spot. Then Ibn Zubayr came and stood beside me, and he kept pressing against me until he pushed me out of that place. Then he prayed four units there.

حدثنا أبو معاوية حدثنا الأعمش عن عمارة

عن أبي الشعثاء قال

خرجت حاجا فدخلت البيت فلما كنت عند الساريتين مضيت حتى لزقت بالحائط قال وجاء ابن عمر حتى قام إلى جنبي فصلى أربعا قال فلما صلى قلت له أين صلى رسول الله ﷺ من البيت قال فقال هاهنا أخبرني أسامة بن زيد أنه صلى قال قلت فكم صلى قال على هذا أجدني ألوم نفسي أني مكثت معه عمرا ثم لم أسأله كم صلى فلما كان العام المقبل قال خرجت حاجا قال فجئت حتى قمت في مقامه قال فجاء ابن الزبير حتى قام إلى جنبي فلم يزل يزاحمني حتى أخرجني منه ثم صلى فيه أربعا
