"I heard 'Aishah say: 'The Messenger of Allah ﷺ would give me the vessel and I would drink from it, when I was menstruating, then I would give it to him and he would look for the place where I had put my mouth and put that to his mouth.'"  

سَمِعْتُ عَائِشَةَ تَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ يُنَاوِلُنِي الإِنَاءَ فَأَشْرَبُ مِنْهُ وَأَنَا حَائِضٌ ثُمَّ أُعْطِيهِ فَيَتَحَرَّى مَوْضِعَ فَمِي فَيَضَعُهُ عَلَى فِيهِ  

"I would drink when I was menstruating, then I would hand it to the Prophet ﷺ, and he would put his mouth where mine had been and drink. And I would nibble at a bone on which some bits of meat were left when I was menstruating, then I would give it to the Prophet ﷺ and he would put his mouth where my mouth had been."  

كُنْتُ أَشْرَبُ مِنَ الْقَدَحِ وَأَنَا حَائِضٌ فَأُنَاوِلُهُ النَّبِيَّ ﷺ فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيَّ فَيَشْرَبُ مِنْهُ وَأَتَعَرَّقُ مِنَ الْعَرْقِ وَأَنَا حَائِضٌ فَأُنَاوِلُهُ النَّبِيَّ ﷺ فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيَّ
