Sahih al-Bukhari 5548Book 73, Hadith 4
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم دَخَلَ عَلَيْهَا وَحَاضَتْ بِسَرِفَ، قَبْلَ أَنْ تَدْخُلَ مَكَّةَ وَهْىَ تَبْكِي فَقَالَ " مَا لَكِ أَنَفِسْتِ ". قَالَتْ نَعَمْ. قَالَ " إِنَّ هَذَا أَمْرٌ كَتَبَهُ اللَّهُ عَلَى بَنَاتِ آدَمَ، فَاقْضِي مَا يَقْضِي الْحَاجُّ غَيْرَ أَنْ لاَ تَطُوفِي بِالْبَيْتِ ". فَلَمَّا كُنَّا بِمِنًى أُتِيتُ بِلَحْمِ بَقَرٍ، فَقُلْتُ مَا هَذَا قَالُوا ضَحَّى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ أَزْوَاجِهِ بِالْبَقَرِ.
that the Prophet (ﷺ) entered upon her when she had her menses at Sarif before entering Mecca, and she was weeping (because she was afraid that she would not be able to perform the Hajj). The Prophet (ﷺ) said, "What is wrong with you? Have you got your period?" She said, "Yes." He said, "This is a matter Allah has decreed for all the daughters of Adam, so perform all the ceremonies of Hajj like the others, but do not perform the Tawaf around the Ka`ba." `Aisha added: When we were at Mina, beef was brought to me and I asked, "What is this?" They (the people) said, "Allah's Messenger (ﷺ) has slaughtered some cows as sacrifices on behalf of his wives."
