al-ghāfilāt: women who are unaware of the shameful acts for which they are accused—in other words, innocent women.
al-muʾmināt: those who believe in Allah.

Overall meaning of the ḥadīth: The Prophet ﷺ instructs his community to stay clear of seven ruinous crimes. When asked what they are, he explained: associating partners with Allah by setting up rivals to Him in any form—beginning with shirk because it is the gravest sin—killing a soul whose life Allah has made inviolable except with a legitimate reason, engaging in ribā (usury) whether by consuming it or benefiting from it in any manner, encroaching upon the property of a child whose father has died, fleeing from the battlefield when confronting the unbelievers, and accusing free, chaste women of fornication.

Relevance of the ḥadīth to the chapter on sorcery: it is proof that sorcery is forbidden and counts among the deadly major sins.

Lessons derived from the ḥadīth:
1- The prohibition of shirk; it is the greatest of the major sins and the gravest of offenses.
2- The prohibition of sorcery; it is one of the deadly major sins and one of the nullifiers of Islam.
3- The prohibition of unlawfully taking a life.
4- The permissibility of taking a life when a legitimate right exists, such as in cases of legal retribution, apostasy, or adultery committed after a consummated marriage.
5- The prohibition of ribā and the severe danger it entails.
6- The prohibition of violating the property of orphans.
7- The prohibition of fleeing from the battle line.
8- The prohibition of accusing others of fornication or sodomy.
9- Slandering a non-Muslim with such accusations is not counted among the major sins.
