Musannaf Ibn Abi Shayba 8:2562

Abu Bakr narrated to us, he said: Ghundar narrated to us, from Shu'bah, from al-Hakam, from Ibrahim, from 'Abd al-Rahman ibn Yazid, who said: I performed Hajj with 'Abdullah. When he arrived at Jam', he gave the Adhan and the Iqamah, then he prayed Maghrib as three [rak'ahs]. Then he ate dinner, then he gave the Adhan and the Iqamah, and he prayed Isha as two [rak'ahs].
