Sahih Muslim Book - 15, Hadith - 3221

حَدَّثَنِى مُحَمَّدُ بْنُ حَاتِمٍ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنِ ابْنِ جُرَيْجٍ أَخْبَرَنِى الْحَسَنُ بْنُ مُسْلِمٍ عَنْ طَاوُسٍ قَالَ كُنْتُ مَعَ ابْنِ عَبَّاسٍ إِذْ قَالَ زَيْدُ بْنُ ثَابِتٍ تُفْتِى أَنْ تَصْدُرَ الْحَائِضُ قَبْلَ أَنْ يَكُونَ آخِرُ عَهْدِهَا بِالْبَيْتِ. فَقَالَ لَهُ ابْنُ عَبَّاسٍ إِمَّا لاَ فَسَلْ فُلاَنَةَ الأَنْصَارِيَّةَ هَلْ أَمَرَهَا بِذَلِكَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- قَالَ فَرَجَعَ زَيْدُ بْنُ ثَابِتٍ إِلَى ابْنِ عَبَّاسٍ يَضْحَكُ وَهُوَ يَقُولُ مَا أَرَاكَ إِلاَّ قَدْ صَدَقْتَ.

It was narrated that Tawus said: “I was with Ibn Abbas, when Zaid bin Thabit said: ‘Are you ruling that a menstruating woman may leave before the last thing she does is to circumambulate the House? ’ Ibn Abbas said to him: ‘If you want to be certain, ask so-and-so, the Ansari woman, whether the Messenger of Allah (SAW) told her to do that?’ Zaid bin Thabit came back to Ibn Abbas smiling and said: ‘I see that you were telling the truth.’”
