2. is an abbreviated term used for the statement or simply bismillah. Bismillah is really "bi ism Allah" which means, I start in the name of Allah. So the words we say are "bismillah", or more completely:: , and the term we use when referring to these words, but not saying them specifically is the Basmalah.
Wa alaikum assalaam wa rahmatullah.
