Kitáb-i-Aqdas

The penalties for wounding or striking a person depend upon the severity of the injury; for each degree the Lord of Judgement hath prescribed a certain indemnity.   ¶56

While Bahá'u'lláh specified that the extent of the penalty depends upon "the severity of the injury", there is no record of His having set out the details of the size of the indemnity with regard to each degree of offence. The responsibility to determine these devolves upon the Universal House of Justice.
