It is narrated from Abu al-Muthanna al-Juhani that I was present with Marwan bin Hakam when Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) came to him. Marwan bin Hakam asked him: Have you heard from the Messenger of Allah (peace and blessings be upon him) that he forbade blowing into a drink (water, etc.)? Abu Sa'id al-Khudri (may Allah be pleased with him) said to him: Yes! Then a man said: O Messenger of Allah! I am not satisfied (my thirst is not quenched) in one breath! So the Messenger of Allah (peace and blessings be upon him) said: Move the cup away from your mouth, then breathe. He said: I see a straw in it (the drink), so the Messenger of Allah (peace and blessings be upon him) said: Then pour it out.
