Quran

إِنَّآ أَنزَلۡنَٰهُ فِي لَيۡلَةِ ٱلۡقَدۡرِ

Indeed, We sent the Qur'an down during the Night of Decree

وَمَآ أَدۡرَىٰكَ مَا لَيۡلَةُ ٱلۡقَدۡرِ

And what can make you know what is the Night of Decree

لَيۡلَةُ ٱلۡقَدۡرِ خَيۡرٞ مِّنۡ أَلۡفِ شَهۡرٖ

The Night of Decree is better than a thousand months

تَنَزَّلُ ٱلۡمَلَـٰٓئِكَةُ وَٱلرُّوحُ فِيهَا بِإِذۡنِ رَبِّهِم مِّن كُلِّ أَمۡرٖ

The angels and the Spirit descend therein by permission of their Lord for every matter

سَلَٰمٌ هِيَ حَتَّىٰ مَطۡلَعِ ٱلۡفَجۡرِ

Peace it is until the emergence of dawn
