What is the criterion for distinguishing between minor and major sins?

Question:
What is the criterion for minor sins and an example of them?

Answer:
There is disagreement regarding the definition of minor sins. The believer should be wary of all evil deeds in their entirety. It is obligatory for the believer to be wary of all evil deeds, both small and large, so that he does not fall into any of the major sins. We ask Allah for well-being.
The most common definition of a major sin is: one that carries a fixed punishment in this world or a warning in the Hereafter; such as theft, unlawful sexual intercourse, and intoxicants, which carry a fixed punishment in this world or a warning in the Hereafter; and backbiting and talebearing, all of which carry a warning.
Q: What do you say about warning people against minor sins so that people do not become lax?
A: It is obligatory to be wary of all sins, and to consider them major sins so that one is wary of them; because any evil deed that one may think is minor could actually be major; therefore, one must be wary.
