"‏ يَا بِنْتَ أَبِي أُمَيَّةَ، سَأَلْتِ عَنِ الرَّكْعَتَيْنِ بَعْدَ الْعَصْرِ، إِنَّهُ أَتَانِي أُنَاسٌ مِنْ عَبْدِ الْقَيْسِ بِالإِسْلاَمِ مِنْ قَوْمِهِمْ، فَشَغَلُونِي عَنِ الرَّكْعَتَيْنِ اللَّتَيْنِ بَعْدَ الظُّهْرِ، فَهُمَا هَاتَانِ ‏"

That Kuraib, the freed slave of Ibn `Abbas told him that Ibn `Abbas, `Abdur-Rahman bin Azhar and Al-Miswar bin Makhrama sent him to `Aisha saying, "Pay her our greetings and ask her about our offering of the two-rak`at after `Asr Prayer, and tell her that we have been informed that you offer these two rak`at while we have heard that the Prophet (ﷺ) had forbidden their offering." Ibn `Abbas said, "I and `Umar used to beat the people for their offering them." Kuraib added, "I entered upon her and delivered their message to her.' She said, 'Ask Um Salama.' So, I informed them (of `Aisha's answer) and they sent me to Um Salama for the same purpose as they sent me to `Aisha. Um Salama replied, 'I heard the Prophet (ﷺ) forbidding the offering of these two rak`at. Once the Prophet (ﷺ) offered the `Asr prayer, and then came to me. And at that time some Ansari women from the Tribe of Banu Haram were with me. Then (the Prophet (ﷺ) ) offered those two rak`at, and I sent my (lady) servant to him, saying, 'Stand beside him and say (to him): Um Salama says, 'O Allah's Messenger (ﷺ)! Didn't I hear you forbidding the offering of these two rak`at (after the `Asr prayer yet I see you offering them?' And if he beckons to you with his hand, then wait behind.' So the lady slave did that and the Prophet (ﷺ) beckoned her with his hand, and she stayed behind, and when the Prophet (ﷺ) finished his prayer, he said, 'O the daughter of Abu Umaiya (i.e. Um Salama), You were asking me about these two rak`at after the `Asr prayer. In fact, some people from the tribe of `Abdul Qais came to me to embrace Islam and busied me so much that I did not offer the two rak`at which were offered after Zuhr compulsory prayer, and these two rak`at (you have seen me offering) make up for those."
