Can a person be raped without feeling it, and if it was not rape, then what is the interpretation of the presence of blood and discharge?

It is not permissible to falsely accuse a friend. What has been mentioned does not conclusively prove the act occurred, and it is highly improbable for this to happen during sleep without awareness. The discharge might be from the person themselves or a result of pimples. One must abstain from groundless misgivings and imaginary fears. Accusing a friend without evidence is considered a false accusation (qadhf), the punishment for which is eighty lashes and loss of credibility, due to its involvement in accusing an innocent person and spreading indecency, in fulfillment of the Almighty’s saying: "And those who harm believing men and believing women for [something] other than what they have earned, have certainly borne a slander and a manifest sin."
