Does one who commits unlawful sexual intercourse while doing so exit the foundation of faith, or does Islam remain?

The questioner : ...

The Shaykh : Yes, this is the view held by some of the Salaf. Some of them said: In that moment, he has no faith. If he had faith, he would not commit unlawful sexual intercourse while knowing that Allah has forbidden it and named it an abomination. Therefore, he qualified his statement by saying: , and that after the act of unlawful sexual intercourse, faith returns to him immediately. We have spoken about this before, and we said that some scholars say this, while others say: He does not commit unlawful sexual intercourse while he is a believer with complete faith.
