Translation of the verse 60 from Surah Al-hajj : Number of verses 78 - - page 339 - Part 17.
That is so. And whoever has retaliated with the like of that which he was made to suffer, and then has again been wronged, Allah will surely help him. Verily! Allah indeed is Oft-Pardoning, Oft-Forgiving.
That [is so]. And whoever responds [to injustice] with the equivalent of that with which he was harmed and then is tyrannized - Allah will surely aid him. Indeed, Allah is Pardoning and Forgiving.
(22:60) This is about them. As regards the one, who takes vengeance equal to the wrong that had been done to him, and has again been oppressed, Allah will surely help him *104 : Allah is Forgiving and Forbearing. *105
*104) The preceding verses referred to those persecuted people who could not retaliate and here 'the reference is to those victims of persecution who could fight back.
From this verse, Imam Shafi`i has concluded that "retaliation" will be effected in the way as life was taken in the original act. If a person is killed by immersion in water, the killer also should be put to death by immersion in water; or if a person is .burnt to death, the killer also will be burnt to death. The Hanafites dispute this. According to them, retaliation against a murderer will be incurred in one and the same established way no matter how life was taken by the culprit in the original act.
*105) This verse (60) may imply two things:
(1) Allah forgives that "killing" which is done in self-defence, though killing of people is not a good thing in itself. (2) As Allah, Whose slaves the Believers are, is Forgiving and Forbearing, they should also forgive and forbear as far as possible. Though they have the right of retaliation, they should not resort to carnage and massacre.
