What is the meaning of each of the terms "fasiq" (transgressor/sinner), "fajir" (dissolute/wicked), and "the ordinary sinner"? And what is the difference between them?

The differences between "al-fujoor" (immorality/profligacy), "al-fisq" (transgression/disobedience), and "al-ma'siyah" (disobedience/sin) lie in the degree of their severity and their usage. "Al-fujoor" is the most severe and is often used to describe excessive engagement in heinous major sins or treating them with contempt, such as sodomy and incest. As for "al-fisq," it is used for major sins but without this extent, such as theft and consuming usury. "Al-ma'siyah" is the most general and includes every transgression.

When these terms are combined, the order from most severe to least severe is: al-fujoor, then al-fisq, then al-ma'siyah. However, when any of them is used individually, it is permissible to intend the other meanings, though the application of "al-fisq" and "al-fujoor" to minor sins is rare and uncommon, as they usually denote major sins.
