Musnad Ahmad 626:30

Yazid narrated to us, Mas'udi informed us, from Ziyad ibn 'Alaqah, who said: "Al-Mughirah ibn Shu'bah led us in prayer. When he had prayed two rak'ahs, he stood up and did not sit. Those behind him glorified Allah (said 'SubhanAllah') to him, so he signaled to them to stand up. When he finished his prayer, he performed the taslim, then he prostrated two prostrations. Then he said: 'This is how the Messenger of Allah, may Allah bless him and grant him peace, did with us.'"
