4ـ 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).”’
