1. Book of Purification
١۔ كِتَابٌ الطَّهَارَةِ
[Machine] A woman from the wives of the Prophet ﷺ performed ablution with a container of janabah (impurity) water. The Prophet ﷺ stood up to do ghusl (ritual bath) from the same water. She said, "I have already performed ablution with it before you." The Prophet ﷺ said, "Indeed, janabah does not affect the water."
امْرَأَةٌ مِنْ نِسَاءِ النَّبِيِّ ﷺ فَاغْتَسَلَتْ فِي جَفْنَةٍ مِنْ جَنَابَةٍ فَقَامَ النَّبِيُّ ﷺ إِلَى فَضْلِهَا يَسْتَحِمُّ فَقَالَتْ إِنِّي قَدِ اغْتَسَلْتُ فِيهِ قَبْلَكَ؟ فَقَالَ النَّبِيُّ ﷺ «إِنَّهُ لَيْسَ عَلَى الْمَاءِ جَنَابَةٌ» ُ
This tradition has also been narrated on the authority of ‘A’ishah through a different chain. (Using translation from Abū Dāʾūd 99)
عَنِ النَّبِيِّ ﷺ نَحْوَه
