The Messenger of Allah ﷺ was a person of gentle disposition, so when she (A'Isha) wished for a thing, he accepted it (provided it did not contravene the teachings of Islam). So he (in pursuance of her desire for a separate lhram for Umra) sent her with 'Abd al-Rahman b. Abu Bakr and she put on Ihram for 'Umra at al-Tan'im. Matar and Abu Zubair (the two narrators amongst the chain of transmitters) said: Whenever 'A'isha performed Hajj she did as she had done along with Allah's Apostle ﷺ.  

أَنَّ عَائِشَةَ ؓ فِي حَجَّةِ النَّبِيِّ ﷺ أَهَلَّتْ بِعُمْرَةٍ وَسَاقَ الْحَدِيثَ بِمَعْنَى حَدِيثِ اللَّيْثِ وَزَادَ فِي الْحَدِيثِ قَالَ وَكَانَ رَسُولُ اللَّهِ ﷺ رَجُلاً سَهْلاً إِذَا هَوِيَتِ الشَّىْءَ تَابَعَهَا عَلَيْهِ فَأَرْسَلَهَا مَعَ عَبْدِ الرَّحْمَنِ بْنِ أَبِي بَكْرٍ فَأَهَلَّتْ بِعُمْرَةٍ مِنَ التَّنْعِيمِ قَالَ مَطَرٌ قَالَ أَبُو الزُّبَيْرِ فَكَانَتْ عَائِشَةُ إِذَا حَجَّتْ صَنَعَتْ كَمَا صَنَعَتْ مَعَ نَبِيِّ اللَّهِ ﷺ
