Sahih al-Bukhari 1758, 1759
Narrated `Ikrima:
The people of Medina asked Ibn `Abbas about a woman who got her menses after performing Tawafal- 
Ifada. He said, "She could depart (from Mecca)." They said, "We will not act on your verdict and 
ignore the verdict of Zaid." Ibn `Abbas said, "When you reach Medina, inquire about it." So, when 
they reached Medina they asked (about that). One of those whom they asked was Um Sulaim. She told 
them the narration of Safiya (812).
حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا حَمَّادٌ، عَنْ أَيُّوبَ، عَنْ عِكْرِمَةَ، أَنَّ أَهْلَ الْمَدِينَةِ، سَأَلُوا ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ عَنِ امْرَأَةٍ، طَافَتْ ثُمَّ حَاضَتْ، قَالَ لَهُمْ تَنْفِرُ‏.‏ قَالُوا لاَ نَأْخُذُ بِقَوْلِكَ وَنَدَعَ قَوْلَ زَيْدٍ‏.‏ قَالَ إِذَا قَدِمْتُمُ الْمَدِينَةَ فَسَلُوا‏.‏ فَقَدِمُوا الْمَدِينَةَ فَسَأَلُوا، فَكَانَ فِيمَنْ سَأَلُوا أُمُّ سُلَيْمٍ، فَذَكَرَتْ حَدِيثَ صَفِيَّةَ‏.‏ رَوَاهُ خَالِدٌ وَقَتَادَةُ عَنْ عِكْرِمَةَ‏.‏
