Hadith 3713ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ إِسْمَاعِيلَ بْنِ مَرَّارٍ عَنْ يُونُسَ عَنْ سَعِيدِ بْنِ يَسَارٍ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) الْمَرْأَةُ تَرَى الدَّمَ وَهِيَ جُنُبٌ أَ تَغْتَسِلُ مِنَ الْجَنَابَةِ أَمْ غُسْلُ الْجَنَابَةِ وَالْحَيْضِ فَقَالَ قَدْ أَتَاهَا مَا هُوَ أَعْظَمُ مِنْ ذَلِكَ.
3. Ali ibn Ibrahim has narrated from his father from ’Isma‘il ibn Marrar from Yunus from Sa‘id ibn Yasar who has said the following: “I once asked abu ‘Abd Allah (a.s.), about the case of a woman who experiences blood discharge because of Hayd (menses) when she has had sexual relation if she needs Ghusl (bath) because of sexual relation or Ghusl (bath) because of the sexual relation and Hayd (menses). He (the Imam) said, ‘She has experienced something bigger than that (sexual relation).”
