What is the difference between the sects that follow the texts of warning and those that follow the texts of promise?

Question:
Shaykh, do some of the sects, such as the Mu'tazilah, follow the texts of warning, O Shaykh Salih? And the Wa'idiyyah.

Answer:
Those who are severe in crimes and declare people disbelievers; they may declare the one who commits a major sin a disbeliever and are strict in matters of religion. This is a matter of extremism and exaggeration in rulings. Likewise, there are those who are lenient, and they are the Murji'ah. The Murji'ah are lenient regarding sins and disobedience, and they say that a sin does not harm alongside faith, just as obedience does not benefit alongside disbelief.
This is a statement: Yes, obedience does not benefit alongside disbelief. The act of disobedience does not benefit alongside faith. This is from the perspective of the Wa'idiyyah (those who emphasize the texts of warning). A sin does not harm alongside disbelief, just as obedience does not benefit alongside disbelief. It is true that obedience does not benefit alongside disbelief, but to say that a sin does not harm alongside faith is a mistake. A person may be a believer and commit a sin, and it may harm him, and he may be subjected to punishment for it, and he is a believer to the extent of his sin. Yes.
