The Shaykh: And as I said about twenty years ago: "Purification and education."
The student: Yes.

The Shaykh: Purification and education. And I say, with regret, regarding Algeria and the fitnah in Algeria, and you have news of it, twenty-five million Muslims...

The student: If it were possible for us, O Shaykh, to sit.
Another student : We sit... It is an invitation from you, O Shaykh.

The Shaykh: No, I say, I say: I have no objection, as long as it is a session here for listening only, not for asking questions.

He said, "We have no scholars." "O people, you want to establish the Muslim state, and you have no scholars?! How can the Muslim state be established on no knowledge?! Therefore, I insist: it is necessary to have purification and education, and upon that, the Muslim state can be established."
