Do the verse of stoning and the verse of 100 lashes for adulteresses mean that the first applies to married women and the second to unmarried women, and is adultery specifically intercourse, or does it include any wrongful act committed after repentance?

Stoning is the punishment for the married fornicator, and one hundred lashes for the unmarried fornicator. The fornication that necessitates the prescribed punishment (Hadd) is sexual intercourse. As for its preliminaries, such as gazing and touching, these are metaphorical forms of fornication that do not necessitate flogging or stoning. It is more befitting for the person who repents to conceal himself, be sincere in his repentance, and increase in good deeds.
