Al-Furqan - 25:25

وَيَوْمَ تَشَقَّقُ السَّمَاء بِالْغَمَامِ وَنُزِّلَ الْمَلَائِكَةُ تَنزِيلًا
[25:25]
And on the day when the heaven shall burst asunder with the clouds, and the angels shall be sent down descending (in ranks).
The Day the heaven shall be rent asunder with clouds, and angels shall be sent down, descending (in ranks),-
A day when the heaven with the clouds will be rent asunder and the angels will be sent down, a grand descent.
