Only saying assalamu alaikum

Assalamu Alaikum Wa Rahmatullahi wa Barakatuh is it haram to just say assalamu alaikum and not Assalamu Alaikum Wa Rahmatullahi wa Barakatuh? And is it haram to shorten Assalamu alaikum to ASA which stands for assalmu alaikum when texting?

Answer

Wa Alaykum Salaam.

It is not Haraam to say Assalaamu Alaykum.

It is against proper etiquette to abbreviate it in the form of ASA. However we cannot say that it is Haraam.

And Allah Ta'ala knows best.
