[Pooya/Ali Commentary 68:16] To have a mark of stigma on the nose, the most prominent part of the face, is a sign of utmost ignominy. The term khurtum, which signifies the proboscis of an elephant, is applied to its nose because it is regarded as ugly. The culprit is contemptuously compared to a beast. It refers to Walid bin Mughayra on whose nose a wound he received in the battle of Badr remained as a mark of shame and disgrace till his death.
