Jami` at-Tirmidhi Book 26, Hadith 28
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."
This Hadith is Hasan Sahih.
"When the Prophet (ﷺ) drank, he would breathe two times."
This Hadith is Hasan Gharib, we do not know of it except as a narration of Rishdin bin Kuraib.
He said: I asked 'Abdullah bin 'Abdur-Rahman about Rishdin bin Kuraib: "Is he stronger (in narration), or Muhammad bin Kuraib?" He said: "Neither are better to me. Rishdin bin Kuraib is preferred over them to me." He said: I asked Muhammad bin Isma'il about this, so he said: "Muhammad bin Kuraib is preferred over Rishdin bin Kuraib." To me, the correct view is what Abu Muhammad 'Abdullah bin 'Abdur-Rahman said: Rishdin bin Kuraib is more preferred and he is elder. He lived to see Ibn 'Abbas, and they are brothers, and they both have Munkar narrations in their reports."
"The Messenger of Allah (ﷺ) prohibited breathing in the vessel, or blowing into it."
This Hadith is Hasan Sahih.
