Hisham bin 'Urwa هشام بن عروة · The Book of the Times (of Prayer)

'Aishah said: "The Messenger of Allah (ﷺ) never entered upon me after 'Asr but he prayed them (the two Rak'ahs)."

"I heard Masruq and Al-Aswad say: We bear witness that 'Aishah said: 'When the Messenger of Allah (ﷺ) was with me after 'Asr, he would pray them (these two Rak'ahs).'"

"They are two Rak'ahs that I used to pray after Zuhr, but I got distracted and forgot them until I prayed 'Asr."
