Rifā‘ah ibn Rāfi‘ Az-Zuraqi (may Allah be pleased with him) reported that Jibrīl came to the Prophet (may Allah's peace and blessings be upon him) and said: "How do you rate the people who participated in the battle of Badr among you?" He said: "They are from the best of Muslims." or said something similar to that. Jibrīl said: "So are the angels that witnessed the battle of Badr."
شرح الحديث :
The great Companion Rifā‘ah informs us that Jibrīl (peace be upon him) came to the Prophet (may Allah's peace and blessings be upon him) and said to him: What is the status of those who fought in the cause of Allah in the battle of Badr? In this battle, Allah granted His Prophet and the believers who joined him a complete victory. He said: They are the best of the Muslims among us. So Jibrīl (peace be upon him) said: The same can be said about the angels who joined the battle and fought in it.
