Sunan an-Nasai
أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ، قَالَ حَدَّثَنَا عَبْدُ الْوَهَّابِ، عَنْ أَيُّوبَ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنِ ابْنِ أَبِي قَتَادَةَ، عَنْ أَبِيهِ، أَنَّ النَّبِيَّ صلى الله عليه وسلم نَهَى أَنْ يَتَنَفَّسَ فِي الإِنَاءِ وَأَنْ يَمَسَّ ذَكَرَهُ بِيَمِينِهِ وَأَنْ يَسْتَطِيبَ بِيَمِينِهِ .
It was narrated from Ibn Abi Qatadah, from his father, that the Prophet (ﷺ) forbade breathing into the vessel (when drinking), touching one's penis with one's right hand, and cleaning oneself with one's right hand.
