Hadith 15:487
Abu Bakr narrated to us, he said: Waki’ narrated to us, from Salam ibn al-Qasim, from his mother, from Umm Sa’id: She said: I brought a *sahur* (pre-dawn meal) to Ali, and I placed it before him while he was praying. When he finished praying, he said: "Why did you not cover it? Did you see the devil when he lapped from it? Pour it out." And he refused to drink it.
حدثنا أبو بكر قال حدثنا وكيع عن سلام بن القاسم عن أمه عن أم سعيد قالت أتيت عليا بسحور فوضعته بين يديه وهو يصلي فلما صلى قال هلا خمرته هل رأيت الشيطان حين ولغ فيه أهرقيه وأبى أن يشربه
