Musnad Ahmad 25:712

Abu Abd al-Rahman said: I found these hadiths in my father’s book in his own handwriting: Sa’id ibn Muhammad al-Warraq narrated to us, he said: Rishdin ibn Kurayb narrated to us, from his father, from Ibn Abbas, who said: "When the Messenger of Allah, may Allah bless him and grant him peace, drank, he would breathe twice while drinking." And my father wrote after this hadith: "I do not think Abdullah heard this hadith."
