Is there a prohibition against drinking from the mouth of the vessel?

The Shaykh : Is there a prohibition against drinking from the mouth of the vessel?
The student : I do not know.

The Shaykh : I am certain that the prohibition is against drinking from the mouth of the waterskin.
The student: Peace be upon you.

The Shaykh : And peace be upon you. The prohibition against drinking from the mouth of the waterskin is one thing.
The student : And the vessel is another thing.

The Shaykh : And the vessel is another thing — welcome, and how is the group? — ... he says to them, why not.
The student : Yes, Shaykh.

The Shaykh : You told me that you were going to come to pick me up while I was telling them that if you came to pick me up, I would have come alone.
The student : Why, Shaykh?

The Shaykh : I would have come alone.
The student : Why, Shaykh?

The Shaykh : Because no one was invited with me.
The student : They told me, Shaykh.

The Shaykh : What did they tell you?
The student : They told me to bring ... I said I would bring Abd al-Rahman ... .

The Shaykh : ... According to my understanding of the plan, it is either here or at the farm. At the farm, there is a possibility that the invitation is wide; here, there is no such possibility ... .
The student : May Allah reward you with good for this understanding, Shaykh.

The Shaykh: Yes, by Allah.
The student : May Allah preserve you.

The Shaykh : A narrow understanding.
The student : A Salafi understanding.

The Shaykh : ... .
The student : We are as we are, in our blindness.

The Shaykh : You are a blessing to us.
The student : If not for Allah, then you.

The Shaykh : Oh Allah, the important thing is that my son came with me and came with you, the fiancé.

The questioner : ... and he is walking.

The Shaykh: Yes.
