Narrated Abu Sa’id Al Khudri : That the Prophet (ﷺ) prohibited blowing into the drink. A man said: "What about if one sees something floating in the vessel?" He said: "Spill it out (removing that)." He said: "I can not drink in one breath." He said: "Then remove the cup away from your mouth." [Abu 'Eisa said:] This Hadith is Hasan Sahih
