The Rebound of Unjust Curses

In the presented sources, there is no direct reference to a specific influence of the so-called Russian curse on Muslims. However, by analyzing the discussions regarding the mechanism of the curse, one can attempt to reconstruct a general picture of the situation.

For instance, source link txt presents the idea that an undeservedly uttered curse returns to its initiator. It states:
"Know that an undeserved curse spoken against you returns upon the head of the one who dared to utter it. And if you, out of fear of curses, go against conscience, duty, and justice, then you will certainly stray from the Lord and feed the evil that should be thwarted at every opportunity..."

This excerpt indicates that the power of a curse is determined by its utterance without sufficient justification and that it operates in a reverse manner. If this concept is applied to the situation in which Russians are accused of harboring a “curse,” then, according to this logic, its effect (regardless of whom it is directed at) is based on a spiritual law of mutual influence among people.

Additionally, source link txt discusses that a curse directed at individuals living in virtuous faith cannot essentially harm them; on the contrary, if the condemnation is thoughtless and malicious, it turns into a blessing.

It states: "Does a curse affect one who lives for God?

We assert that someone intending to curse those who live virtuously cannot utter a single distressing or repugnant word, but the curse turns into a blessing..."

Based on these notions, if any party (in this case, the Russians) utters a curse, its effect is determined not so much by the nationality of the target, but by the spiritual strength, moral stance, and the true intention behind it. Within such a concept, if Muslims or representatives of any other faith become the object of a curse, the action of this charm would be explained by the general principle: an undeserved curse bears a reverse effect, which may manifest in different ways on those under its influence.

Thus, the influence of a curse in this context can be interpreted as follows: if a curse is spoken without sufficient grounds and from malevolent impulses, it possesses a reverse force—a mechanism of spiritual mutual influence as described in the sources. This means that the effect may not specifically concern Muslims, but rather any people who find themselves in the corresponding spiritual and moral position.

In summary, although a direct connection between the curse attributed to Russians and its impact on Muslims is not traced in the materials, the aforementioned discussions on the mechanism of the curse suggest that its effect is based on a universal spiritual law, in which undeserved condemnation, regardless of its target, carries a reverse consequence.
