Muwatta Imam Malik Book of Hajj, Hadith 237

Yahya related to me from Malik from Hisham ibn Urwa from his father from A'isha umm al-muminin that the Messenger of Allah ﷺ mentioned Safiyya bint Huyy and he was told that she had started her period. The Messenger of Allah ﷺ said, "Perhaps she will delay us." They said, "Messenger of Allah, she has done tawaf," and the Messenger of Allah ﷺ said, "Then she will not delay us."
Malik said that Hisham said that Urwa said that A'isha said, "We have publicized that, so why do people make their women stay on to their inconvenience? If it were as they say, more than six thousand menstruating women would still be in Mina in the morning, all of them having already done the tawaf al- ifada.' "

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ، أَنَّ رَسُولَ اللَّهِ ﷺ ذَكَرَ صَفِيَّةَ بِنْتَ حُيَىٍّ فَقِيلَ لَهُ قَدْ حَاضَتْ . فَقَالَ رَسُولُ اللَّهِ ﷺ " لَعَلَّهَا حَابِسَتُنَا " . فَقَالُوا يَا رَسُولَ اللَّهِ إِنَّهَا قَدْ طَافَتْ . فَقَالَ رَسُولُ اللَّهِ ﷺ " فَلاَ إِذًا " . قَالَ مَالِكٌ قَالَ هِشَامٌ قَالَ عُرْوَةُ قَالَتْ عَائِشَةُ . وَنَحْنُ نَذْكُرُ ذَلِكَ فَلِمَ يُقَدِّمُ النَّاسُ نِسَاءَهُمْ إِنْ كَانَ ذَلِكَ لاَ يَنْفَعُهُنَّ وَلَوْ كَانَ الَّذِي يَقُولُونَ لأَصْبَحَ بِمِنًى أَكْثَرُ مِنْ سِتَّةِ آلاَفِ امْرَأَةٍ حَائِضٍ كُلُّهُنَّ قَدْ أَفَاضَتْ .
