Hazrat Amir Muawiyah once sent a messenger to Hazrat Aisha and inquired whether the Prophet (peace be upon him) had ever performed any prayer after Asr. She replied, "Not with me, but Hazrat Umm Salamah has informed me that the Prophet (peace be upon him) did so, so you should ask her!" Accordingly, they asked Hazrat Umm Salamah (may Allah be pleased with her) this question, and she replied, "Yes, once the Prophet (peace be upon him) performed the Asr prayer and came to my house because it was my turn that day, and he performed two rak'ahs there. I asked, 'O Messenger of Allah, what are these two rak'ahs which you have been commanded to perform?' The Prophet (peace be upon him) replied, 'No, rather these are the rak'ahs which I used to perform after Zuhr, but I became so occupied with the distribution of wealth that the muezzin came to inform me of the Asr prayer, and I did not consider it appropriate to leave them (so I performed them now).'"
