Sahih Bukhari Volume 1, Book 6, Hadith 294

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا سُفْيَانُ، قَالَ سَمِعْتُ عَبْدَ الرَّحْمَنِ بْنَ الْقَاسِمِ، قَالَ سَمِعْتُ الْقَاسِمَ، يَقُولُ سَمِعْتُ عَائِشَةَ، تَقُولُ خَرَجْنَا لاَ نَرَى إِلاَّ الْحَجَّ، فَلَمَّا كُنَّا بِسَرِفَ حِضْتُ، فَدَخَلَ عَلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم وَأَنَا أَبْكِي قَالَ ‏"‏ مَا لَكِ أَنُفِسْتِ ‏"‏‏.‏ قُلْتُ نَعَمْ‏.‏ قَالَ ‏"‏ إِنَّ هَذَا أَمْرٌ كَتَبَهُ اللَّهُ عَلَى بَنَاتِ آدَمَ، فَاقْضِي مَا يَقْضِي الْحَاجُّ، غَيْرَ أَنْ لاَ تَطُوفِي بِالْبَيْتِ ‏"‏‏.‏ قَالَتْ وَضَحَّى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ نِسَائِهِ بِالْبَقَرِ‏

Narrated By Al-Qasim : 'Aisha said, "We set out with the sole intention of performing Hajj and when we reached Sarif, (a place six miles from Mecca) I got my menses. Allah's Apostle came to me while I was weeping. He said 'What is the matter with you? Have you got your menses?' I replied, 'Yes.' He said, 'This is a thing which Allah has ordained for the daughters of Adam. So do what all the pilgrims do with the exception of the Taw-af (Circumambulation) round the Ka'ba." 'Aisha added, "Allah's Apostle sacrificed cows on behalf of his wives."
