Musannaf Ibn Abi Shaybah 36037 — The affair of al-Qadisiyyah

Ibrahim said: A man fled from the Battle of al-Qadisiyyah or Mihran or one of those other battles and came to Sayyiduna Umar (may Allah be pleased with him), and he said: "I am ruined; I fled from the battlefield." Sayyiduna Umar said to him: "Not at all. I am your rallying party (the group you may fall back on)."
