Narrated Ibn Abbas:

A menstruating woman was allowed to leave Mecca if she had done Tawaf-al-Ifada. Tawus (a sub-narrator) said from his father, "I heard Ibn 'Umar saying that she would not depart. Then later I heard him saying that the Prophet had allowed them (menstruating women) to depart."

حَدَّثَنَا مُسْلِمٌ، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا ابْنُ طَاوُسٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ رُخِّصَ لِلْحَائِضِ أَنْ تَنْفِرَ إِذَا أَفَاضَتْ. قَالَ وَسَمِعْتُ ابْنَ عُمَرَ، يَقُولُ إِنَّهَا لاَ تَنْفِرُ. ثُمَّ سَمِعْتُهُ يَقُولُ بَعْدُ إِنَّ النَّبِيَّ ﷺ رَخَّصَ لَهُنَّ.
