Ruling on mutilating the disbelievers

One of the brother mujahideen from Bosnia and Herzegovina came to us and spoke about the enemies and mutilating them.So one of the brothers objected to him and said: This is not permissible and it is forbidden.The brother who came from jihad replied to him and said: Is this permissible before killing them, but after killing them, mutilating them is not permissible? What is your opinion? May Allah reward you with good.

Whoever holds that mutilating the disbelievers is not permissible if they are found, in any case, relies on the generality of the hadith in which the Messenger of Allah (peace and blessings be upon him) used to advise those he sent out from the armies and expeditions: "Do not mutilate",But this generality is specified by the saying of Allah the Exalted: [al-Baqarah:194] If they do that to us, then we have the right to do to them what they do to us; because if we hold back from this, it would result in humiliation, and they will not benefit from it if we do not mutilate them to the extent that they refrain from mutilating us in the future,And otherwise, if we expected that, we would say: Considering this benefit, we do not mutilate them.
