Allah (glorified and exalted be He) has supernumerary angels who rove about seeking out gatherings in which Allah’s name is being invoked: they sit with them and fold their wings round each other, filling that which is between them and between the lowest heaven.
When [the people in the gathering] depart, [the angels] ascend and rise up to heaven.
He (the Prophet PBUH) said: Then Allah (mighty and sublime be He) asks them – [though] He is most knowing about them: From where have you come?
And they say: We have come from some servants of Yours on Earth: they were glorifying You (Subhanallah), exalting you (Allahu-Akbar), witnessing that there is no god but You (La ilaha illa llah), praising You (Al-Hamdu Lillah), and asking [favours] of You.
He says: And what do they ask of Me?
They say: They ask of You Your Paradise.
He says: And have they seen My Paradise?
They say: No, O Lord.
He says: And how would it be were they to have seen My Paradise!
They say: And they ask protection of You.
He says: From what do they ask protection of Me?
They say: From Your Hell-fire, O Lord.
He says: And have they seen My Hell-fire?
They say: NO.
He says: And how would it be were they to have seen My Hell-fire:
They say: And they ask for Your forgiveness.
He (the Prophet PBUH) said: Then He says: I have forgiven them and I have bestowed upon them what they have asked for,and I have granted them sanctuary from that from which they asked protection.
He (the Prophet PBUH) said: They say: O Lord, among them is So-and-so, a much sinning servant, who was merely passing by and sat down with them.
He (the Prophet PBUH) said: And He says: And to him [too] I have given forgiveness: he who sits with such people shall not suffer.
It was related by Muslim (also by al-Bukhari, at-Tirmidhi, and an-Nasa’i).
