The Holy Quran : Chapter 97 : Al-Qadr (The Majesty)

بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ

In the name of Allah, Most Gracious, Most Merciful.

 إِنَّا أَنْزَلْنَاهُ فِي لَيْلَةِ الْقَدْرِ

97:1. We have indeed revealed this (Message) in the Night of Power:

وَمَا أَدْرَاكَ مَا لَيْلَةُ الْقَدْرِ

97:2. And what will explain to thee what the Night of Power is?

لَيْلَةُ الْقَدْرِ خَيْرٌ مِنْ أَلْفِ شَهْرٍ

97:3. The Night of Power is better than a thousand Months.

تَنَزَّلُ الْمَلَائِكَةُ وَالرُّوحُ فِيهَا بِإِذْنِ رَبِّهِمْ مِنْ كُلِّ أَمْرٍ

97:4. Therein come down the angels and the Spirit by Allah´s permission, on every errand:

سَلَامٌ هِيَ حَتَّىٰ مَطْلَعِ الْفَجْرِ

97:5. Peace! ...This until the rise of Morning.
