What is the difference between the accusation of zina (unlawful sexual intercourse) and its confession in the hadith of the young man?

The questioner : Yes, yes. I mean, in the other hadith, the hadith of the young man who committed zina with the woman, the Messenger (peace and blessings be upon him) ordered that he be flogged and exiled, and he suspended the stoning of the woman pending her confession, even though here the son, or the father of the son, confessed that he had committed zina with her. And yet, he did not stone her based on the young man's confession. What is the reason?

The Shaykh : Because the young man's claim that he committed zina with her is an accusation that is not accepted. As for the man's confession that his son committed zina, and the son may be present, that is a confession. So there is a difference between an accusation and a confession. This man's statement regarding the woman is an accusation, and his statement regarding his son is a confession.
