Hadith 3534ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ خَالِدٍ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ قَالَ سُئِلَ أَبُو عَبْدِ الله (عَلَيْهِ الْسَّلام) وَأَنَا حَاضِرٌ عَنِ الْمَرْأَةِ تَرَى الصُّفْرَةَ فَقَالَ مَا كَانَ قَبْلَ الْحَيْضِ فَهُوَ مِنَ الْحَيْضِ وَمَا كَانَ بَعْدَ الْحَيْضِ فَلَيْسَ مِنْهُ.
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn Khalid from al-Qasim ibn Muhammad from Ali ibn abu Hamzah who has said the following: “Abu ‘Abd Allah (a.s.), was asked, when I was in his presence, about the case of a woman who experiences a discharge of yellowish color. He (the Imam) said, ‘What is before Hayd (menses) is of Hayd (menses) and what is after Hayd (menses) is not Hayd (menses).”’
