Muwatta Imam Malik Book of Hajj, Hadith 233

Yahya related to me from Malik from Abd ar-Rahman ibn al-Qasim from his father that A'isha said, "I came to Makka at the time of my period so I did not do tawaf of the House or go between Safa and Marwa. I complained to the Messenger of Allah ﷺ and he said, 'Do what the people doing hajj do except do not do tawaf of the House and go between Safa and Marwa until you are pure.' "
Malik said, concerning a woman who entered ihram for umra at the time of hajj, and she arrived in Makka during her period and so could not do tawaf of the House, "When she fears that the time (for hajj) is getting close, she gets into ihram for the hajj and sacrifices an animal. She is like someone who combines the hajj and the umra. One tawaf is enough for her. If a women starts her period after she has already done tawaf of the House and prayed, she does say between Safa and Marwa and stops at Arafa and Muzdalifa and stones the jamras but she does not do the tawaf al-ifada until she is pure and has finished her menses."

حَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّهَا قَالَتْ قَدِمْتُ مَكَّةَ وَأَنَا حَائِضٌ، فَلَمْ أَطُفْ بِالْبَيْتِ وَلاَ بَيْنَ الصَّفَا وَالْمَرْوَةِ فَشَكَوْتُ ذَلِكَ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ " افْعَلِي مَا يَفْعَلُ الْحَاجُّ غَيْرَ أَنْ لاَ تَطُوفِي بِالْبَيْتِ وَلاَ بَيْنَ الصَّفَا وَالْمَرْوَةِ حَتَّى تَطْهُرِي " .
