Penalties for striking/wounding depend on injury's severity

"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. He is, in truth, the Ordainer, the Mighty, the Most Exalted. We shall, if it be Our Will, set forth these payments in their just degrees--this is a promise on Our part, and He, verily, is the Keeper of His pledge, the Knower of all things."

(Bahá'u'lláh, Kitáb-i-Aqdas, par. 56)

Forbidden in the Book of God to strike another

“Ye have been forbidden in the Book of God to engage in contention and conflict, to strike another, or to commit similar acts whereby hearts and souls may be saddened.”

(Bahá'u'lláh, Kitáb-i-Aqdas, par. 148)

Beware lest hands cause harm to anyone

“Incline your hearts to the counsels given by the Most Exalted Pen and beware lest your hands or tongues cause harm unto anyone among mankind.”

(Bahá'u'lláh, Tablets of Bahá'u'lláh, Lawh-i-Dunyá, p. 85

No record of Bahá'u'lláh setting out details so the Universal House of Justice will determine

"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."
