Roaming angels seek out gatherings of remembrance

Al-Tirmidhi relates from Abu Hurayra (may God be pleased with him) that the Prophet ﷺ said that God said: Allah has roaming angels in the land beyond the recording ones; when they find people remembering Allah they call "come to what you seek," come and surround them up to the lowest heaven, and God says: what were My servants doing? They say: we left them praising You, magnifying You, declaring You one and seeking Your forgiveness — the last of what they say; then tranquility descends on them, mercy envelops them, the angels surround them, and God mentions them among those with Him. In Ibn Rajab's Forty commentary, from Abu Hurayra: whenever people gather remembering Allah, tranquility descends on them, mercy envelops them, the angels surround them, God mentions them among those with Him, and whoever is slow in deed is not hastened by lineage ¹ Tirmidhi 3600 ² Forty 36.

In these two hadith qudsi the angels have a special charge in gatherings of remembrance: they come to them from the earth, surround their people up to heaven, then tranquility and mercy descend and God mentions them with Himself ^{1 2}.

Two parallel hadith qudsi in Jami' al-Tirmidhi and Ibn Rajab's commentary; the Jinn & Devils Browser shows them in the angels section ^{1 2}.
