[Machine] The Messenger of Allah, ﷺ , entered upon me after Asr prayer and performed two rak'ahs (units of prayer). I said, "O Messenger of Allah, what are these two rak'ahs?" He said, "I used to pray them after Dhuhr but something occupied me from praying them until I prayed Asr, so I prayed them now."

دَخَلَ عَلَيَّ رَسُولُ اللهِ ﷺ بَعْدَ الْعَصْرِ فَصَلَّى رَكْعَتَيْنِ فَقُلْتُ يَا رَسُولَ اللهِ مَا هَاتَانِ الرَّكْعَتَانِ قَالَ «كُنْتُ أُصَلِّيهُمَا بَعْدَ الظُّهْرِ فَجَاءَنِي حَالٌ فَشَغَلَنِي عَنْهُمَا حَتَّى صَلَّيْتُ الْعَصْرَ فَصَلَّيْتُهُمَا الْآنَ»
