Read surah Al-Qadr

إِنَّاۤ أَنزَلۡنَـٰهُ فِی لَیۡلَةِ ٱلۡقَدۡرِ 

BEHOLD, from on high have We bestowed this [divine writ] on Night of Destiny.

وَمَاۤ أَدۡرَىٰكَ مَا لَیۡلَةُ ٱلۡقَدۡرِ 

And what could make thee conceive what it is, that Night of Destiny?

لَیۡلَةُ ٱلۡقَدۡرِ خَیۡرࣱ مِّنۡ أَلۡفِ شَهۡرࣲ 

The Night of Destiny is better than a thousand months:

تَنَزَّلُ ٱلۡمَلَـٰۤئِكَةُ وَٱلرُّوحُ فِیهَا بِإِذۡنِ رَبِّهِم مِّن كُلِّ أَمۡرࣲ 

in hosts descend in it the angels, bearing divine inspiration by their Sustainer's leave; from all [evil] that may happen

سَلَـٰمٌ هِیَ حَتَّىٰ مَطۡلَعِ ٱلۡفَجۡرِ 

does it make secure, until the rise of dawn.
