Ati reported that he witnessed Saeed bin Jubayr at Jam. He stood up, and I believe he gave the call to prayer, then prayed Maghrib as three units. After giving the closing salam, he prayed Isha as two units. Then he said, "Ibn Umar did the same thing for us in this very place, and Ibn Umar said, 'The Messenger of Allah ﷺ did the same thing for us in this very place.'"
