Hanzalah bin Ali Aslami narrates from a man of Banu Dail, who says: I performed the Zuhr prayer at home, then I took the camels out to take them to the shepherd. As I passed by the Messenger of Allah, peace and blessings be upon him, he was leading the people in the Zuhr prayer. I passed by and did not pray with him. When I had driven the camels ahead and returned, this matter was conveyed to the Messenger of Allah, peace and blessings be upon him. He asked me: O so-and-so! When you passed by us, what prevented you from praying with us? I said: O Messenger of Allah! I had already prayed at home. He, peace and blessings be upon him, said: Even if (you have already prayed at home, when you find the prayer with the Imam, then pray again).
