In the last Hajj of Messenger of Allah ﷺ I assumed the Ihram for Hajj along with Allah Apostle. I was one of those who intended Tamattuʿ (to perform Hajj and ʿUmra) and did not take the Hadi (animal for sacrifice) with me. I got my menses and was not clean till the night of ʿArafa I said, "O Allah's Apostle! It is the night of the day of ʿArafat and I intended to perform the Hajj Tamattuʿ with ʿUmra. Messenger of Allah ﷺ told me to undo my hair and comb it and to postpone the ʿUmra. I did the same and completed the Hajj. On the night of Al-Hasba (i.e. place outside Mecca where the pilgrims go after finishing all the ceremonies of Hajj at Mina) he (the Prophet) ordered ʿAbdur Rahman (ʿAisha's brother) to take me to at-Tanʿim to assume the lhram for ʿUmra in lieu of that of Hajj-at-Tamattuʿ which I had intended to perform.  

أَهْلَلْتُ مَعَ رَسُولِ اللَّهِ ﷺ فِي حَجَّةِ الْوَدَاعِ فَكُنْتُ مِمَّنْ تَمَتَّعَ وَلَمْ يَسُقِ الْهَدْىَ فَزَعَمَتْ أَنَّهَا حَاضَتْ وَلَمْ تَطْهُرْ حَتَّى دَخَلَتْ لَيْلَةُ عَرَفَةَ فَقَالَتْ يَا رَسُولَ اللَّهِ هَذِهِ لَيْلَةُ عَرَفَةَ وَإِنَّمَا كُنْتُ تَمَتَّعْتُ بِعُمْرَةٍ فَقَالَ لَهَا رَسُولُ اللَّهِ ﷺ انْقُضِي رَأْسَكِ وَامْتَشِطِي وَأَمْسِكِي عَنْ عُمْرَتِكِ فَفَعَلْتُ فَلَمَّا قَضَيْتُ الْحَجَّ أَمَرَ عَبْدَ الرَّحْمَنِ لَيْلَةَ الْحَصْبَةِ فَأَعْمَرَنِي مِنَ التَّنْعِيمِ مَكَانَ عُمْرَتِي الَّتِي نَسَكْتُ
