Musannaf Ibn Abi Shaybah 4846 — A man leading people in Zuhr and Asr

Kathir bin Aflah said: I reached the mosque and had not yet prayed Maghrib. Meanwhile the congregation stood up, and I prayed with them, thinking it was the Maghrib prayer, but I found out that they were praying Isha. So I first prayed Maghrib and then Isha. Then I asked the elders about this, and they instructed me to do just what I had done.
