Sahih al-Bukhari 1783
Narrated Aisha:
We set out along with Allah's Messenger (ﷺ) shortly before the appearance of the new moon (crescent) of the 
month of Dhi-l-Hijja and he said to us, "Whoever wants to assume Ihram for Hajj may do so; and 
whoever wants to assume Ihram for `Umra may do so. Hadn't I brought the Hadi (animal for 
sacrificing) (with me), I would have assumed Ihram for `Umra." (`Aisha added,): So some of us 
assumed Ihram for `Umra while the others for Hajj. I was amongst those who assumed Ihram for 
`Umra. The day of `Arafat approached and I was still menstruating. I complained to the Prophet (ﷺ) 
(about that) and he said, "Abandon your `Umra, undo and comb your hair, and assume Ihram for 
Hajj;." When it was the night of Hasba, he sent `Abdur Rahman with me to at-Tan`im and I assumed 
Ihram for `Umra (and performed it) in lieu of my missed `Umra.
حَدَّثَنَا مُحَمَّدُ بْنُ سَلاَمٍ، أَخْبَرَنَا أَبُو مُعَاوِيَةَ، حَدَّثَنَا هِشَامٌ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ خَرَجْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم مُوَافِينَ لِهِلاَلِ ذِي الْحَجَّةِ فَقَالَ لَنَا ‏"‏ مَنْ أَحَبَّ مِنْكُمْ أَنْ يُهِلَّ بِالْحَجِّ فَلْيُهِلَّ وَمَنْ أَحَبَّ أَنْ يُهِلَّ بِعُمْرَةٍ فَلْيُهِلَّ بِعُمْرَةٍ، فَلَوْلاَ أَنِّي أَهْدَيْتُ لأَهْلَلْتُ بِعُمْرَةٍ ‏"‏‏.‏ قَالَتْ فَمِنَّا مَنْ أَهَلَّ بِعُمْرَةٍ، وَمِنَّا مَنْ أَهَلَّ بِحَجٍّ، وَكُنْتُ مِمَّنْ أَهَلَّ بِعُمْرَةٍ، فَأَظَلَّنِي يَوْمُ عَرَفَةَ، وَأَنَا حَائِضٌ، فَشَكَوْتُ إِلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَ ‏"‏ ارْفُضِي عُمْرَتَكِ، وَانْقُضِي رَأْسَكِ وَامْتَشِطِي، وَأَهِلِّي بِالْحَجِّ ‏"‏‏.‏ فَلَمَّا كَانَ لَيْلَةُ الْحَصْبَةِ أَرْسَلَ مَعِي عَبْدَ الرَّحْمَنِ إِلَى التَّنْعِيمِ، فَأَهْلَلْتُ بِعُمْرَةٍ مَكَانَ عُمْرَتِي‏.‏
