Musannaf Ibn Abi Shaybah 35993 — The battle of Abu Ubayd

Qays said: Sayyiduna Abu Ubayd bin Mas'ud (may Allah be pleased with him) was with his companions in the Battle of Mihran. After they had crossed, the bridge was cut and they were martyred. Qays said: In the Battle of Mihran, some people, among whom was Sayyiduna Khalid bin Urfutah (may Allah be pleased with him), said to Sayyiduna Jarir (may Allah be pleased with him): "O Jarir! We will never leave our position." He said: "O Jarir! We should cross this river." I said: "Do you want them to do to us what they did to Abu Ubayd? We are a people who do not know how to swim. We will not leave our territory until Allah Almighty judges between us and them." Then the polytheists crossed it, and on that day Mihran was killed while he was at a place called Nukhaylah.
