Yahya related to me from Malik from Hisham ibn Urwa from his father from Zaynab bint Abi Salama that Umm Salama, the wife of the Prophet ﷺ said, "Umm Salama, the wife of Abu Talha al-Ansari, came to the Messenger of Allah ﷺ and said, 'Messenger of Allah! Allah is not ashamed of the truth-does a woman have to do ghusl if she has had an erotic dream?' He said, 'Yes, if she sees any liquid.' "

حَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ زَيْنَبَ بِنْتِ أَبِي سَلَمَةَ، عَنْ أُمِّ سَلَمَةَ، زَوْجِ النَّبِيِّ ﷺ أَنَّهَا قَالَتْ جَاءَتْ أُمُّ سُلَيْمٍ امْرَأَةُ أَبِي طَلْحَةَ الأَنْصَارِيِّ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ اللَّهَ لاَ يَسْتَحْيِي مِنَ الْحَقِّ هَلْ عَلَى الْمَرْأَةِ مِنْ غُسْلٍ إِذَا هِيَ احْتَلَمَتْ فَقَالَ " نَعَمْ إِذَا رَأَتِ الْمَاءَ " .
