Sahih Ibn Khuzaymah

Ibrahim bin Suwaid narrates that Hazrat Alqamah (may Allah have mercy on him) led us in five rak'ahs of Zuhr prayer. After saying salam, the people said, "O Abu Shibl, you have led five rak'ahs." He said, "Never, I did not do so." The people said, "Why not (you did lead five rak'ahs)." I (Ibrahim bin Suwaid) was sitting on one side among the people and was still a young boy. I said, "Why not, you have led five rak'ahs." He said to me, "O one-eyed (blind in one eye), are you also saying the same?" I replied, "Yes." So he turned towards the qiblah and performed two prostrations, then said salam. Then he said that Sayyiduna Abdullah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) led us in five rak'ahs. When he finished the prayer, the people began to talk quietly among themselves. The Messenger of Allah (peace and blessings be upon him) asked, "What has happened to you?" They said, "O Messenger of Allah (peace and blessings be upon him), has the prayer been increased?" He said, "No." They said, "Indeed, you have led five rak'ahs." So he turned towards the qiblah and performed two prostrations, then said salam. Then he said, "Indeed, I am a human being; I forget just as you forget."
