Islamic Interpretation
A lancet in a dream symbolizes a person whose words cut like a blade, representing slander, sharp speech, and the harm caused by the tongue, and inflicting a horizontal cut with it signifies backbiting, spreading false accusations, and sowing discord and hostility among people, while making a vertical wound indicates praising someone, speaking truthfully in their favor, and using words to heal rifts, unite hearts, and restore harmony among others.
