Abdullah bin Umar reported,

The Messenger of Allah ﷺ entered the House along with Bilal, Usama bin Zayd, and Uthman bin Talha. They closed the door and remained inside for a while, then he came out. When the door was opened, I was the first to enter, and I asked Bilal where the Messenger of Allah ﷺ had prayed.Bilal replied, "Between the two front pillars."But I forgot to ask him how many units of prayer he performed.

حدثنا يحيى عن عبيد الله حدثني نافع

عن عبد الله قال

دخل رسول الله ﷺ البيت هو وبلال وأسامة بن زيد وعثمان بن طلحة فأجافوا الباب ومكثوا ساعة ثم خرج فلما فتح كنت أول من دخل فسألت بلالا أين صلى رسول الله ﷺ فقال بين العمودين المقدمين ونسيت أن أسأله كم صلى
