Musannaf Ibn Abi Shaybah

Hazrat Qabeesah bin Dhu’ayb says that I was performing prayer when Hazrat Abu Hurairah passed by me. He said to me, “Make a separation (fasl).” I could not understand what he was saying. When I finished the prayer, I asked, “In what should I make a separation?” He said, “Make a separation between the day prayer and the night prayer.”
