If he enters a masjid and prays only Fard, this is enough and he doesn’t need to pray 2 rak’ah tahiyatul masjid unless he wants to sit before praying the fard.

On journey one should pray tahiyat ul masjid when entering mosque as on journey one needs to pray only fard (in reduced form) as per my knowledge?
