Those who abstain from the great sins and shameful deeds except a thought in mind; indeed, your Lord is wide-forgiving, He knows you well when He created you from the earth and when you were hidden in the bellies of your mothers, so you don’t purify yourselves, He knows best the one who is heedful.
The sins committed deliberately, knowing the soul is included in the heinous sins. "Except the thought in mind" means a thought came to do a shameful deed, but was not brought into practice. That means by thinking in the mind only, it won’t be included in the great sins. But it should not lead to sin. See explanation 4: 31-32. ‘Indeed, your Lord is wide-forgiving’ means even though great sins happen from one before receiving Adhikr, which distinguishes good and evil, but he, by identifying the sins from Adhikr, if he seeks forgiveness from Allah for them and gives enough ransom, then the Merciful Lord Allah will forgive the sins to him. See explanation 25: 68-72; and 39: 53-55.
It is the Three-Time Knower Lord who created the heavens, earth, and all in between them, including mankind in six days, who has decided in which country, in which era, with which parents, in which sex, and in which shape everyone should take birth. So you shouldn’t purify yourselves. That means you shouldn’t act as pious before others, hiding your sins and offenses; you shouldn’t be a braggart, and there shouldn’t be a condition of forgetting the Lord at any time and anywhere. But by transforming his or her Jinn soulmate into a believer utilizing Adhikr—the Three-Time Knowledge, as well as Food, Cloth, and Sight of the human soul—everyone should purify himself/herself. It is possible only by confirming himself as a believer, conceiving the character of the Impartial Lord, and thus being free from the covetousness of the soul, and conveying the Message of the Lord Adhikr to all mankind. Then only he or she becomes approving of Allah as the Impartial One who taught mankind Adhikr. See explanation 4: 49-50; 7: 178; and 36: 6, 19.
