We have indeed revealed this (Message) in the Night of Power:
1إِنَّا أَنزَلْنَاهُ فِي لَيْلَةِ الْقَدْرِ
And what will explain to thee what the night of power is?
2وَمَا أَدْرَاكَ مَا لَيْلَةُ الْقَدْرِ
The Night of Power is better than a thousand months.
3لَيْلَةُ الْقَدْرِ خَيْرٌ مِّنْ أَلْفِ شَهْرٍ
Therein come down the angels and the Spirit by Allah's permission, on every errand:
4تَنَزَّلُ الْمَلَائِكَةُ وَالرُّوحُ فِيهَا بِإِذْنِ رَبِّهِم مِّن كُلِّ أَمْرٍ
Peace!... This until the rise of morn!
5سَلَامٌ هِيَ حَتَّىٰ مَطْلَعِ الْفَجْرِ
