We bear testimony to the fact that 'A'isha said: Never was there a day that he (the Holy Prophet) was with me and he did not observe two rak'ahs of prayer in my house, i. e. two rak'ahs after the Asr. (Using translation from Muslim 835d)
عَنِ الْأَسْوَدِ وَمَسْرُوقٍ أَنَّهُمَا قَالَا نَشْهَدُ عَلَى عَائِشَةَ أَنَّهَا قَالَتْ مَا كَانَ يَوْمُهُ الَّذِي يَكُونُ عِنْدِي إِلَّا صَلَّاهُمَا رَسُولُ اللهِ ﷺ فِي بَيْتِي تَعْنِي الرَّكْعَتَيْنِ بَعْدَ الْعَصْرِ
