The Cleansing of Impurities - Section 1
وَعَن الْأسود وَهَمَّام عَنْ عَائِشَةَ قَالَتْ: كُنْتُ أَفْرُكُ الْمَنِيَّ مِنْ ثَوْبِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ. رَوَاهُ مُسلم وَبِرِوَايَةِ عَلْقَمَةَ وَالْأَسْوَدِ عَنْ عَائِشَةَ نَحْوَهُ وَفِيهِ: ثمَّ يُصَلِّي فِيهِ
Al-Aswad and Hammam reported ‘A'isha as saying, “I used to rub the prostatic fluid from the garment of God's messenger." Muslim transmitted it. A version of ‘Alqama and al-Aswad quotes ‘A'isha to the same effect, with the addition that he then prayed in it.
