Bulugh al-Maram, Book 1, Hadith 102 (English) ⓘ

Narrated Abu Qatada (rad): Allah’s Messenger said: “Nobody should touch his pennies with his right hand when urinating, and should not clean himself (from defecation or urine) using his right hand and should not breathe in the utensil (he is drinking from).” [Agreed upon. This version is of Muslim].

وَعَنْ أَبِي قَتَادَةَ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ لَا يُمْسِكَنَّ أَحَدُكُمْ ذَكَرَهُ بِيَمِينِهِ, وَهُوَ يَبُولُ, وَلَا يَتَمَسَّحْ مِنْ اَلْخَلَاءِ بِيَمِينِهِ, وَلَا يَتَنَفَّسْ فِي اَلْإِنَاءِ } مُتَّفَقٌ عَلَيْهِ, وَاللَّفْظُ لِمُسْلِم ٍ (114)‏.‏ ‏1 ‏- صحيح.‏ رواه البخاري (153)‏، ومسلم (267)‏ (63)‏.‏
