Musannaf Ibn Abi Shaybah

Hazrat Yahya bin Saeed (may Allah have mercy on him) narrates that Hazrat Mu’adh bin Rifa’ah (may Allah be pleased with him) said: Indeed, an angel came to the service of the Messenger of Allah (peace and blessings be upon him) and asked: What is the status of your companions of Badr among you? Upon this, the Prophet (peace and blessings be upon him) said: They are the most virtuous among the people. So the angel submitted: In the same way, among us, those angels are the most virtuous who were present at the Battle of Badr.
