He spoke on the meaning of the hadith: (Cursing a Muslim is open sinfulness . . . . . . .) .

The Shaykh : The word for disbelief that appears in those texts cannot be interpreted as meaning leaving the religion. For example, there is the well-known hadith in the two Sahihs, narrated by 'Abdullah ibn Mas'ud (may Allah be pleased with him), who said: The Messenger of Allah (peace and blessings be upon him) said: Fighting him is disbelief. This is a variation in Arabic rhetorical style, because if someone were to say, "Cursing a Muslim and fighting him is open sinfulness," that would be a correct statement, as open sinfulness is disobedience and departure from obedience. However, the Messenger (peace be upon him), being the most eloquent of those who spoke the Arabic language, said: Do you think it is permissible for us to interpret the first part of this hadith, "Cursing a Muslim is open sinfulness," with the open sinfulness mentioned in the second or third phrase of the previous verse ? "Those are the open sinners." And "Cursing a Muslim is open sinfulness." We say that open sinfulness may also be a synonym for disbelief that means leaving the religion, or it may be a synonym for disbelief that does not mean leaving the religion, but rather what the interpreter of the Qur'an said is "disbelief less than disbelief." This hadith confirms that disbelief can have this meaning. Why? Because Allah (Mighty and Majestic) mentioned in the Noble Qur'an the well-known verse Here, our Lord (Mighty and Majestic) mentioned the transgressing faction that fights the successful faction, the righteous faction, the believing faction, and yet He did not rule that they are disbelievers, even though the hadith says: So fighting him is disbelief, meaning less than disbelief, as Ibn 'Abbas said in his interpretation of the previous verse. Thus, fighting a Muslim by a Muslim is transgression, aggression, open sinfulness, and disbelief.
