حَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ زَيْنَبَ بِنْتِ أَبِي سَلَمَةَ، عَنْ أُمِّ سَلَمَةَ، زَوْجِ النَّبِيِّ صلى الله عليه وسلم أَنَّهَا قَالَتْ جَاءَتْ أُمُّ سُلَيْمٍ امْرَأَةُ أَبِي طَلْحَةَ الأَنْصَارِيِّ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ اللَّهَ لاَ يَسْتَحْيِي مِنَ الْحَقِّ هَلْ عَلَى الْمَرْأَةِ مِنْ غُسْلٍ إِذَا هِيَ احْتَلَمَتْ فَقَالَ " نَعَمْ إِذَا رَأَتِ الْمَاءَ " .
Yahya related to me from Malik from Hisham ibn Urwa from hisfather from Zaynab bint Abi Salama that Umm Salama, the wife of theProphet, may Allah bless him and grant him peace, said, "Umm Salama,the wife of Abu Talha al-Ansari, came to the Messenger of Allah, mayAllah bless him and grant him peace, and said, 'Messenger of Allah!Allah is not ashamed of the truth-does a woman have to do ghusl if shehas had an erotic dream?' He said, 'Yes, if she sees any liquid.' " Translation Not Available
