What is the ruling on mutual cursing inside the mosque, knowing that the mosque has sacred dignities?

If the intention is to play with weapons in the mosque, there is no harm in it, based on what is reported in the Two Sahihs from Aisha, that the Prophet (peace be upon him) used to watch the Abyssinians playing with their spears in the mosque. Imam An-Nawawi permitted playing with weapons and similar instruments of war in the mosque, and this can be extended to include whatever aids in jihad and acts of righteousness. However, the time and place should be considered so as not to stir up discord, especially since some scholars believe that this ruling has been abrogated.
