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. (Using translation from Nasāʾī 48)
أَنَّ النَّبِيَّ ﷺ نَهَى أَنْ يَتَنَفَّسَ فِي الْإِنَاءِ أَوْ يَمَسَّ ذَكَرَهُ بِيَمِينِهِ أَوْ يَسْتَطِيبَ بِيَمِينِهِ
The Messenger of Allah (way peace be upon him) forbade (us) to breathe into the venel, to touch the penis with the right hand and to wipe after relieving with right hand.
أَنَّ النَّبِيَّ ﷺ نَهَى أَنْ يَتَنَفَّسَ فِي الإِنَاءِ وَأَنْ يَمَسَّ ذَكَرَهُ بِيَمِينِهِ وَأَنْ يَسْتَطِيبَ بِيَمِينِهِ
