“When anyone of you drinks, let him not breathe into the vessel. If he wants to continue drinking, let him move the vessel away (in order to breathe) then bring it back, if he wants.” (Using translation from Ibn Mājah 3427)
"إِذَا شَرِبَ أحدُكم فلا يتنَفسْ في الإناءِ فإِذَا أرادَ أن يعودَ فَليُنَحِّ الإِناءَ ثُمَّ ليَعُدْ إنْ كانَ يريدُ" .
