(Al-Qiyama) 75 : 2
وَلَا أُقْسِمُ بِالنَّفْسِ اللَّوَّامَةِ

Nay; I do swear by the self-accusing conscience.

Every soul has been taught Adhikr from the Paradise itself. Since Adhikr which is the Splendid Book mentioned in verse 41: 41 is codified as a Book today, the Kuffar-Fujjar-mentioned in verses 83: 34 and 36 who hide and reject Adhikr after receiving It, will witness against their soul as indeed they were disbelievers vide verse 7: 37; and on the Day of Judgement vide verse 6: 130. At the time of their death Lord will tell them that you received My verses, you rejected them, you were arrogant, and you were among the disbelievers as told in verse 39: 59. Without admitting himself that I am a disbeliever, Impartial Lord will never send anyone to the Hell. So the one in thousand believer by utilizing Adhikr-the Insight-should confirm himself that he is a believer to the Paradise. See explanation 36: 69-70 and 64: 2.
