Narrated Bukair:

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 Rakat while we have heard that the Prophet 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 forbidding the offering of these two Rakat. Once the Prophet 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 ) offered those two Rakat, and I sent my (lady) servant to him, saying, 'Stand beside him and say (to him): Um Salama says, 'O Allah's Apostle! Didn't I hear you forbidding the offering of these two Rakat (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 beckoned her with his hand, and she stayed behind, and when the Prophet finished his prayer, he said, 'O the daughter of Abu Umaiya (i.e. Um Salama), You were asking me about these two Rakat 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 Rakat which were offered after Zuhr compulsory prayer, and these two Rakat (you have seen me offering) make up for those."

حَدَّثَنَا يَحْيَى بْنُ سُلَيْمَانَ، حَدَّثَنِي ابْنُ وَهْبٍ، أَخْبَرَنِي عَمْرٌو،. وَقَالَ بَكْرُ بْنُ مُضَرَ عَنْ عَمْرِو بْنِ الْحَارِثِ، عَنْ بُكَيْرٍ، أَنَّ كُرَيْبًا، مَوْلَى ابْنِ عَبَّاسٍ حَدَّثَهُ أَنَّ ابْنَ عَبَّاسٍ وَعَبْدَ الرَّحْمَنِ بْنَ أَزْهَرَ وَالْمِسْوَرَ بْنَ مَخْرَمَةَ أَرْسَلُوا إِلَى عَائِشَةَ ـ رضى الله عنها ـ فَقَالُوا اقْرَأْ عَلَيْهَا السَّلاَمَ مِنَّا جَمِيعًا، وَسَلْهَا عَنِ الرَّكْعَتَيْنِ بَعْدَ الْعَصْرِ، وَإِنَّا أُخْبِرْنَا أَنَّكِ تُصَلِّيهَا، وَقَدْ بَلَغَنَا أَنَّ النَّبِيَّ ﷺ نَهَى عَنْهَا، قَالَ ابْنُ عَبَّاسٍ وَكُنْتُ أَضْرِبُ مَعَ عُمَرَ النَّاسَ عَنْهُمَا. قَالَ كُرَيْبٌ فَدَخَلْتُ عَلَيْهَا، وَبَلَّغْتُهَا مَا أَرْسَلُونِي، فَقَالَتْ سَلْ أُمَّ سَلَمَةَ. فَأَخْبَرْتُهُمْ، فَرَدُّونِي إِلَى أُمِّ سَلَمَةَ بِمِثْلِ مَا أَرْسَلُونِي إِلَى عَائِشَةَ، فَقَالَتْ أُمُّ سَلَمَةَ سَمِعْتُ النَّبِيَّ ﷺ يَنْهَى عَنْهُمَا، وَإِنَّهُ صَلَّى الْعَصْرَ ثُمَّ دَخَلَ عَلَىَّ وَعِنْدِي نِسْوَةٌ مِنْ بَنِي حَرَامٍ مِنَ الأَنْصَارِ، فَصَلاَّهُمَا، فَأَرْسَلْتُ إِلَيْهِ الْخَادِمَ فَقُلْتُ قُومِي إِلَى جَنْبِهِ فَقُولِي تَقُولُ أُمُّ سَلَمَةَ يَا رَسُولَ اللَّهِ أَلَمْ أَسْمَعْكَ تَنْهَى عَنْ هَاتَيْنِ الرَّكْعَتَيْنِ فَأَرَاكَ تُصَلِّيهِمَا. فَإِنْ أَشَارَ بِيَدِهِ فَاسْتَأْخِرِي. فَفَعَلَتِ الْجَارِيَةُ، فَأَشَارَ بِيَدِهِ، فَاسْتَأْخَرَتْ عَنْهُ، فَلَمَّا انْصَرَفَ قَالَ " 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 ".
