An electrophilic substitution reaction on benzene does not always result in monosubstitution. While electrophilic substituents usually withdraw electrons from the aromatic ring and thus deactivate it against further reaction, a sufficiently strong electrophile can perform a second or even a third substitution. This is especially the case with the use of catalysts.

benzene doesnt react by addition : It would destroy aromatic stabilisation

Aromatic compounds react by substitution reactions.

These preserve the stability of aromatic sextet ( i.e., overall it remains aromatic )
