Musannaf Ibn Abi Shayba 3:2104

Ibn Fudayl narrated to us, from Husayn, from Ibrahim and Ali ibn Mudrik, they both said: Alqama led us in prayer. He led us in five [units of prayer]. When he performed the taslim, they said to him: "You prayed five." He turned to a man from the people and said: "Is that so, O one-eyed man?" He said: "Yes." So he performed two prostrations.
