I have seen some people write “saw” after the name of our prophet Mohammed (PBUH) instead of “PBUH”. Though there is nothing wrong in “saw” but in my opinion it is better if we say (PBUH) because it is the language we are using and thus makes it easier for people especially non-Muslims to understand. Moreover, it shows as much respect as “saw”. Furthermore, we can also say (Peace Be Upon Him). However, this is not very important.
yeh muhammed u are right :)
