Abu al-Zinad (may Allah have mercy on him) narrates from the jurists of Madinah that when the nose is completely cut off, or its tip is cut off, there is the full diyah (blood money) for it; likewise, if the male organ is cut off entirely, or its glans is cut off, there is the full diyah; and for the two testicles there is the full diyah, and for whichever one of them is injured there is half the diyah.
