Laylat al-Qadr (لَيْلَةِ الْقَدْرِ)
The Night of Predestination
إِنَّا أَنْزَلْناهُ فِي لَيْلَةِ الْقَدْرِ{1}
Surely, We Revealed it during the Laylat Al-Qadar (The Night of Predestination) [97:1]
عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنِ ابْنِ بُكَيْرٍ عَنْ زُرَارَةَ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ ( عليه السلام ) التَّقْدِيرُ فِي لَيْلَةِ تِسْعَ عَشْرَةَ وَ الْإِبْرَامُ فِي لَيْلَةِ إِحْدَى وَ عِشْرِينَ وَ الْإِمْضَاءُ فِي لَيْلَةِ ثَلَاثٍ وَ عِشْرِينَ
A number of our companions, from Ahmad Bin Muhammad, from Ali Bin Al Hakam, from Ibn Bukeyr, from Zurara who said,
Abu Abdullah-asws said: ‘The Ordainment is during the night of the 19th, and the Confirmation is during the night of the 21st, and the accomplishment is during the night of the 23rd’.[1]
