Musannaf Ibn Abi Shaybah 5698 — A man whose ablution breaks on Friday

Waki' said: I asked Sufyan: If a man began the Friday prayer with the imam, but his ablution broke and he went to make ablution, and when he came back the imam had already finished the prayer, what should he do? He said: If he has not spoken to anyone, he should pray two rak'ahs.
