Sahih Muslim , Book 18, Hadith 43 (In-Book) ⓘ

Ibn Abbas (Allah be pleased with them) is reported to have said: I intended to ask Umar about those two ladies who had pressed for (worldly riches) during the lifetime of the Prophet, and I kept waiting for one year, but found no suitable opportunity with him until I happened to accompany him to Mecca. And as he reached Marr al Zahran he went away to answer the call of nature, and he said (to me): Bring me a jug of water, and I took that to him. After having answered the call of nature, as he came back, I began to pour water (over his hands and feet), and I remembered (this event of separation of Allah's Apostle [may peace be upon him] from his wives). So I said to him: Commander of the Faithful, who are the two ladies (who had pressed the Prophet [may peace be upon him] for providing comforts of life) and I had not yet finished my talk when he said: They were 'A'isha and Hafsa.

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَزُهَيْرُ بْنُ حَرْبٍ، - وَاللَّفْظُ لأَبِي بَكْرٍ - قَالاَ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ يَحْيَى بْنِ سَعِيدٍ، سَمِعَ عُبَيْدَ بْنَ حُنَيْنٍ، - وَهُوَ مَوْلَى الْعَبَّاسِ - قَالَ سَمِعْتُ ابْنَ عَبَّاسٍ، يَقُولُ كُنْتُ أُرِيدُ أَنْ أَسْأَلَ، عُمَرَ عَنِ الْمَرْأَتَيْنِ اللَّتَيْنِ تَظَاهَرَتَا عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَلَبِثْتُ سَنَةً مَا أَجِدُ لَهُ مَوْضِعًا حَتَّى صَحِبْتُهُ إِلَى مَكَّةَ فَلَمَّا كَانَ بِمَرِّ الظَّهْرَانِ ذَهَبَ يَقْضِي حَاجَتَهُ فَقَالَ أَدْرِكْنِي بِإِدَاوَةٍ مِنْ مَاءٍ فَأَتَيْتُهُ بِهَا فَلَمَّا قَضَى حَاجَتَهُ وَرَجَعَ ذَهَبْتُ أَصُبُّ عَلَيْهِ وَذَكَرْتُ فَقُلْتُ لَهُ يَا أَمِيرَ الْمُؤْمِنِينَ مَنِ الْمَرْأَتَانِ فَمَا قَضَيْتُ كَلاَمِي حَتَّى قَالَ عَائِشَةُ وَحَفْصَةُ ‏.‏
