It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her); she said: "I never saw the Messenger of Allah (peace and blessings be upon him) pray after Asr except once. Once some people came to him (peace and blessings be upon him) after Zuhr and kept him occupied until he (peace and blessings be upon him) forgot, so he (peace and blessings be upon him) did not pray anything after Zuhr until he had prayed Asr. Then when he had prayed Asr, he came to my house and prayed two rak'ahs."
