Musannaf Ibn Abi Shaybah 39462 — The great Battle of Badr, how it came

Sa'id bin al-Musayyib says that on the day of Badr five of the Muhajirun from Quraysh were killed: Sayyiduna Mihja' (may Allah be pleased with him), the freed slave of Sayyiduna Umar (may Allah be pleased with him), who charged saying: "I am Mihja', and to my Lord alone I hasten in fear." And Sayyiduna Dhu al-Shimalayn, Sayyiduna Ibn Bayda, Sayyiduna Ubaydah bin al-Harith and Sayyiduna Amir bin Abi Waqqas (may Allah be pleased with them) were killed.
