Musannaf Ibn Abi Shayba 36:165

Shadhan narrated to us, he said: Hammad bin Salamah narrated to us, from Ali bin Zaid, from Sa’id bin al-Musayyib, he said: Five men from the Emigrants of Quraysh were killed on the day of Badr: Mihja’, the freed slave of Umar, who was carrying [his sword] and saying, "I am Mihja’, and to my Lord I return." And Dhu al-Shimalayn was killed, and Ibn Bayda’, and Ubaydah bin al-Harith, and ‘Amir bin Abi Waqqas.
