If you see shears in your dream, it often signifies a warning about someone potentially tarnishing another's reputation. The presence of shears suggests that you or someone else is capable of distinguishing between truth and lies. This dream may serve as a caution that you or someone around you is speaking dishonestly. It highlights the need for vigilance and honesty in your life.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Shears" (page 383) â resolved via the equivalent "Scissors" entry.
In a dream, scissors mean slander and causing harm to someone's reputation without regard for the truth. Scissors in a dream also represent a legal guardian who discerns between true and false. Holding a pair of scissors in a dream means delivering a brother for one's first born son, or having two businesses feeding one another, unless if one is unmarried, then holding a pair of scissors, or a nail clipper in a dream means getting married. If one sees a pair of scissors falling from the skies in a dream, they represent the scissors of destiny and the end of his life in this world. Clipping people's beards in a dream means backbiting them. A pair of scissors in a dream also represents business partners. Sheep shearing with a pair of scissors in a dream means prosperity. Holding a pair of scissors in a dream also means a dispute that requires a judge or a mediator.
