Rifa'ah bin Rafi' Az-Zuraqi (May Allah be pleased with him) said:
Jibril (Gabriel) came to the Prophet (ﷺ) and asked him: "How do you estimate among you those who participated in the battle of Badr?" He replied, "They were the best of Muslims" (or he may have said something similar to that). Jibril said: "The same is the case with the angels who were at Badr."[Al- Bukhari].
