أَخْبَرَنَا أَحْمَدُ، حَدَّثَنَا ابْنُ الْمُبَارَكِ، عَنْ يُونُسَ، عَنْ الزُّهْرِيِّ فِي الْمَرْأَةِ تَرَى الطُّهْرَ فَتَسْمَعُ السَّجْدَةَ، قَالَ: "لَا تَسْجُدُ حَتَّى تَغْتَسِلَ".
It is narrated from Imam Zuhri, may Allah have mercy on him, regarding a woman who has become pure and hears a verse of prostration, that until she performs ghusl, she will not perform the prostration.
