Wa Alaykum as salam sister,
Invoking ALLAH [swt]'s names is perfectly preferable and is an act of great importance. If I could give you some examples from the glorious Qur'an
Say (O Muhammad ): "Invoke Allah or invoke Ar-Rahman (Allah), by whatever name you invoke Him (it is the same), for to Him belong the Best Names) (17:110),)
and,
(And ask (O Muhammad ) those of Our Messengers whom We sent before you: "Did We ever appoint alihah (gods) to be worshipped besides Ar-Rahman (Most Gracious, Allah)'') (43:45).
