أَخْبَرَنَا يَعْلَى ، عَنْ مُحَمَّدِ بْنِ إِسْحَاق ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ ، عَنْ صَاحِبَتِهِ فَاطِمَةَ بِنْتِ مُحَمَّدٍ ، وَكَانَتْ فِي حِجْرِ عَمْرَةَ ، قَالَتْ : أَرْسَلَتْ امْرَأَةٌ مِنْ قُرَيْشٍ إِلَى عَمْرَةَ بِكُرْسُفَةِ قُطْنٍ فِيهَا كَالصُّفْرَةِ تَسْأَلُهَا : هَلْ تَرَى إِذَا لَمْ تَرَ الْمَرْأَةُ مِنْ الْحِيضَةِ إِلَّا هَذَا أَنْ قَدْ طَهُرَتْ؟ فَقَالَتْ :" لَا، حَتَّى تَرَى الْبَيَاضَ خَالِصًا "

Ya'la told us, on the authority of Muhammad ibn Ishaq, on the authority of Abdullah ibn Abi Bakr, on the authority of his companion Fatima bint Muhammad, and she was in Hijr. Amra, she said: A woman from the Quraysh sent to Amra with a piece of cotton in it that looked like yellow, asking her: Do you see if the woman does not see? From menstruation, unless she has become pure? She said: “No, until you see pure white.”
