The Virtues of the Night of Al-Qadr (the Decree)

Allah informs that He sent the Qur'an down during the Night of Al-Qadr, and it is a blessed night about which Allah says,

إِنَّآ أَنزَلْنَـهُ فِى لَيْلَةٍ مُّبَـرَكَةٍ

Verse [ 5] سَلَامٌ (Peace it is till the rising of dawn.) The word Salam [ peace ] stands for a complete sentence meaning 'it is all peace, equanimity and complete goodness, having no evil in it.' [ Qurtubi ]. Some scholars treat the word Salamun as a sentence qualifying مِّن كُلِّ أَمْرٍ min kulli amrin, meaning 'the angels come with every such matter which is good and peace'. [ Mazhari ].

هِيَ حَتَّىٰ مَطْلَعِ الْفَجْرِ‌ The concluding expression of the verse means the blessings of the Night of Qadr are not restricted to any particular part of the night. They start descending at the fall of night and continue till the break of dawn.
