Is it permissible for a woman to use specific means and tools as an alternative to an unattainable marriage, and is that considered better than falling intozina, just as masturbation is used as an alternative for a man while awaiting a marriage opportunity?

The only legitimate way to satisfy one's desires is through marriage. Anything else is an aggression and a deviation, as Allah Almighty says: "And those who guard their private parts Except from their wives or those their right hands possess, for indeed, they are not to be blamed But whoever seeks beyond that, then those are the transgressors." Therefore, no other means may be used. The sin is not to be trivialized just because it is less severe than fornication. Rather, a Muslim must avoid suspicious situations and adhere to the limits of Islamic law. Whoever is unable to marry should practice chastity and fast.
