Al-Matalib al-'Aliyah 3976 — The virtue of Abd al-Rahman bin Awf

Humayd bin Abd al-Rahman narrates from his mother, Sayyidah Umm Kulthum bint Uqbah (may Allah be pleased with her) (who was among the earliest women emigrants), that Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) fell into such a severe swoon that the people thought his soul had departed. So Sayyidah Umm Kulthum (may Allah be pleased with her) went out to the mosque to seek Allah's help through patience and prayer, as has been commanded (in the Qur'an). Then, when he regained consciousness, he asked: "Did I faint?" The people said: Yes. He said: "You have spoken the truth. (While I was unconscious) two angels came to me and said: Come, let us take your case before the One who is the Mighty, the Trustworthy. Then another angel said: Take him back, for he is among those fortunate people for whom happiness was written while they were in their mothers' wombs, and his children will yet benefit from him for as long as Allah wills." So he lived for a month after this incident and then passed away.
Abu Usamah said that the two men here means the angels who came in human form, as Allah, the Mighty and Majestic, says: "And had We made him an angel, We would have made him a man" [Surah al-An'am: 9], that is: in human form.
