An-Naba' - 78:38

يَوْمَ يَقُومُ الرُّوحُ وَالْمَلَائِكَةُ صَفًّا لَّا يَتَكَلَّمُونَ إِلَّا مَنْ أَذِنَ لَهُ الرحْمَنُ وَقَالَ صَوَابًا
[78:38]
The day on which the spirit and the angels shall stand in ranks; they shall not speak except he whom the Beneficent Allah permits and who speaks the right thing.
The Day that the Spirit and the angels will stand forth in ranks, none shall speak except any who is permitted by (Allah) Most Gracious, and He will say what is right.
On the day when the angels and the Spirit stand arrayed, they speak not, saving him whom the Beneficent alloweth and who speaketh right.
