Does the Muslim Who Commits a Major Sin Leave the Fold of Ahlus-Sunnah?

This clearly shows that the questioner did not attend my lessons, this is the first time he is attending. We have explained throughout all of these years, and we said: The Muslim from Ahlus-Sunnah wal-Jamaa’h, even if he is an evildoer, he is still from Ahlus-Sunnah wal-Jamaa’h, as long as he did not commit kufr (disbelief). He is from Ahlus-Sunnah wal-Jamaa’h. However, he is an evildoer and deficient in Imaan (belief/faith). And he is not considered to have left Islam nor Imaan. He is from Ahlus-Sunnah wal-Jamaa’h.
