Yes brother, rasoolullah sallallaahu alaihi wa sallam never used to say verbal inetentions (niyyahs).

See the following links for further information:

Allah knows best.

In addition to Ukhtee Insane...
Even it is said that saying niyah is bida'a by few scholars.
When you have done Wudhu and came to masjid or placed musalla, your niyah is already there to offer sala of some specific time.
