Hadith #5

5ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادِ بْنِ عُثْمَانَ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ سَأَلْتُهُ عَنِ الْمَرْأَةِ تَرَى فِي الْمَنَامِ مَا يَرَى الرَّجُلُ قَالَ إِذَا أَنْزَلَتْ فَعَلَيْهَا الْغُسْلُ وَإِنْ لَمْ تُنْزِلْ فَلَيْسَ عَلَيْهَا الْغُسْلُ.

5. A number of our people have narrated from Ahmad ibn Muhammad from ibn abu ‘Umayr from Hammad ibn ‘Uthman from al- Halabiy who has said the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about a woman who experiences in her dream what a man does. He (the Imam) said, ‘If she experiences discharge Ghusl (bath) is necessary on her; if there is no discharge, Ghusl (bath) is not necessary.’”
