You say: “Oh mankind, the Truth has come to you from your Lord, so whoever is guided is only guided for his own sake, and whoever goes astray only goes astray for her own sake, and I am not a custodian upon you”.
The Truth mentioned in 256 places such as in 2: 147; 3: 60; 7: 8-9; 11: 17; 17: 81; 21: 24; 25: 33 and 39: 41 is Adhikr. If male or female follows and testifies Adhikr, he/she will be admitted into Paradise. If male or female falsifies and hides Adhikr after receiving It, he/she will be admitted into the Hell. The Impartial Lord has codified Adhikr as a Book through the Three-Time-Knower mentioned in verse 25: 59. So, nobody can blame the Lord, Satan, Prophets or anyone for one’s astray. It is Lord Who has sent His Messenger with Guidance and the True way of life, to be it supreme upon all other ways of life, even though the Mushriks are hating It as explained in verse 9: 33. The believer transforms his Jinn soulmate into a believer with Adhikr, and he will only die as a true Muslim as explained in verses 3: 102 and 16: 89. All other hypocrites and Kuffar (Fujjar) will witness against their soul as “indeed, they were disbelievers” at the time of death and on the Day of Judgment as explained in 10: 60. Any Fujjar who didn’t testify Adhikr, he is following falsehood. Since Trial is done with Adhikr on the Day of Judgment, he will be among the losers as told in verse 40: 78. See the explanations 2: 119; 3: 41; 4: 104 and 10: 94.
