سنن أبي داود

Abu Burdah b. Abl Musa al-Asha’ri said: ‘Abd Allah b. ‘Umar said to me: Did you hear your father narrating a tradition from the Messenger of Allah (ﷺ) about an hour on Friday (when supplication is accepted by Allah)? I said: Yes, I heard it. I heard the Messenger of Allah (ﷺ) say: This hour is found during the period when the imam is seated (for giving Friday sermon) until the prayer is finished.

Abu Dawud said: By sitting is meant sitting on the pulpit.
