Yahya related to me from Malik from Zayd ibn Aslam that a man questioned the Messenger of Allah ﷺ saying, "What is permitted me from my wife when she is menstruating?" The Messenger of Allah ﷺ said, "Let her wrap her waist-wrapper round herself tightly, and then what is above that is your concern."  

أَنَّ رَجُلاً سَأَلَ رَسُولَ اللَّهِ ﷺ فَقَالَ مَا يَحِلُّ لِي مِنِ امْرَأَتِي وَهِيَ حَائِضٌ فَقَالَ رَسُولُ اللَّهِ ﷺ لِتَشُدَّ عَلَيْهَا إِزَارَهَا ثُمَّ شَأْنَكَ بِأَعْلاَهَا  

[Machine] A man asked the Messenger of Allah ﷺ , "What is permissible for me to do with my wife while she is menstruating?" He replied, "Cover her with a cloth and do whatever you would normally do with her except for intercourse."  

سَأَلَ رَجُلٌ رَسُولَ اللَّهِ ﷺ فَقَالَ مَا يَحِلُّ لِي مِنَ امْرَأَتِي وَهِيَ حَائِضٌ؟ قَالَ «لِتَشُدَّ عَلَيْهَا إِزَارَهَا ثُمَّ شَأْنَكَ بِأَعْلَاهَا»
