حَدَّثَنَا عَفَّانُ حَدَّثَنَا وُهَيْبٌ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ طَاوُسٍ عَنْ أَبِيهِ أَنَّهُ سَمِعَ ابْنَ عُمَرَ يَقُولُ فِي أَوَّلِ أَمْرِهِ إِنَّهَا لَا تَنْفِرُ قَالَ ثُمَّ سَمِعْتُ ابْنَ عَبَّاسٍ يَقُولُ رَخَّصَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَهُنَّ
مسند امام احمد بن حنبل · Hadith 5765
'Abdullah ibn Tawoos narrated from his father that he heard rbn 'Umar initially say that (a woman) should not leave for home (if she had completed Hajj then got her menses before doing the farewell tawaaf). He said: Then I heard Ibn 'Umar say: The Messenger of Allah (PBUH) granted them (menstruating women) a concession.
