Umar, Letter to Usama bin Zaid
“ He asks, suppose the offending person should have but one eye, or one hand, ought be to be deprived of the one, because he had struck out an eye or cut off another man’s hand that had two? Again, how would it be possible for a judge to inflict a punishment, which should be exactly the same with the injury, since that stroke might prove mortal to one man, which was not so to another; and so a man might pay for a wound which was not mortal, with the loss of his life? ”
