Check the very huge mistake  we make by wrong pronunciation. .. .Specially influenced by Pakistani style ...who I have observed.... . pronounce the salaam as shown in the fourth line ...

"  AS SALAMU ALAIKUM - (TUM PAR SALAMATI HO) -- CORRECT - "

 - SAAM- O- OALAIKUM - (TUM BARBAAD HO JAO)

 - ASAAM- O- ALAIKUM - (TUM KU MAUT AJAAYE)

 - ASSA- E- KUM - (TUM KHUSHI KU TARSO)

  - SLAM- LE- KUM - (TUM PE LAANAT HO)

THESE ARE BASIC MISTAKES AND EVEN AS MUSLIMS WE DONT KNOW HOW TO  SAY "ASSALAMU- ALAIKUM",

SO BE CAREFUL ABOUT  IT.
