The prescribed corporal punishments are not to be carried out in mosques; nor should retribution be carried out in them

The great Companion Hakīm ibn Hizām (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) forbade the implementation of all prescribed corporal punishments in mosques. This includes the prescribed punishments that are related to Allah or to the human beings, because this represents a violation of the sanctity of mosques, and it is possible that they get dirty from wounds or ritual impurities.

Moreover, mosques are built for the sole purpose of prayer and remembering Allah, not for the implementation of the prescribed corporal punishments. The Hadīth is evidence on the prohibition of carrying out corporal punishments and retaliation inside mosques.

This is because it is established in the fundamentals of Fiqh that forbidding doing something implies its prohibition by default, unless there is a factor that impedes the default meaning and makes it imply otherwise - which is not the case here.
