The questioner : Peace be upon you, O Shaykh.

The Shaykh : And upon you be peace and the mercy of Allah.

The questioner: I hope we haven't tired you out, but it is no trouble.

The Shaykh: Praise be to Allah, I am well.

The questioner: May Allah reward you with good. The question is regarding i'tikaf (spiritual retreat in the mosque); what is the validity of the statement I heard that i'tikaf is not permissible except in three mosques: the Haram in Makkah, the one in Madinah, and al-Aqsa?

The Shaykh: This is not a statement [of a scholar], but rather the statement of the Infallible.

The questioner : (peace and blessings be upon him).
