Abu Dawud Book 20, Hadith Number 3721.

Chapter : What should be said when drinking milk.

Narated By Abdullah ibn Abbas : I was in the house of Maymunah. The Apostle of Allah (PBUH) accompanied by Khalid ibn al-Walid entered. Two roasted long-tailed lizards (dabb) placed on the sticks were brought to him. The Apostle of Allah (PBUH) spat. Khalid said: I think that you abominate it, Apostle of Allah. He said: Yes. Then the Apostle of Allah (PBUH) was brought milk, and he drank (it). The Apostle of Allah (PBUH) then said: When one of you eats food, he should say: O Allah, bless us in it, and give us food (or nourishment) better than it. When he is given milk to drink he should say: O Allah! bless us in it and give us more of it, for no food or drink satisfies like milk.

Abu Dawud said: This is Musaddad’s version.
