Musannaf Ibn Abi Shaybah 7803 — The ruler who delays the prayer beyond

Muslim said: In the time of Ziyad I used to sit with Masruq and Abu Ubaydah in the mosque. When the time of Zuhr entered, the two of them prayed Zuhr, then sat down; and when the muezzin gave the call and the imam came out, they prayed with the imam as well. And the two of them did the same in the Asr prayer.
