Amr bin Shu'aib narrates from his father, from his grandfather: The Prophet Muhammad (peace be upon him) gave the verdict regarding the nose that: "When it is completely cut off, its compensation (diyah) will be complete (equal to the full diyah of a life), and if only its front part is cut off, then half the diyah will be given."
