(Ankabooth ) 29 : 3
وَلَقَدْ فَتَنَّا الَّذِينَ مِنْ قَبْلِهِمْ ۖ فَلَيَعْلَمَنَّ اللَّهُ الَّذِينَ صَدَقُوا وَلَيَعْلَمَنَّ الْكَاذِبِينَ
And surely We have tested those before them, and Lord Allah will surely know those who are truthful and who are liars.
Lord has fastened upon everyone’s neck a Recording Book which will not omit anything unless it is recorded in It. On the Day of Judgment, It will be produced as a Spread Open Book and it will be told to each: “Read your Book, Today, you are enough for your Reckoning” as explained in verses 17: 13-14 and 18: 49. Whoever testified Adhikr in this world will receive his Recording Book in his right hand in the Hereafter, and whoever falsifies It, he will receive his Recording Book in his left hand in the Hereafter as explained in verses 7: 8-9. See explanation 16: 111.
