P.B.U.H.

These letters are abbreviations for the phrase Peace Be   Upon Him which is the translation of the Arabic expression Alaihis   Salam or A.S., which is an expression that is said when the name of a prophet is mentioned. This expression is widely used by  English speaking Muslims. It is to be noticed here that this expression does not give the full meaning of "Salla Allahu Alaihi  Wa Sallam". Therefore it is recommended that people do not use   (p.b.u.h.) after the name of prophet Muhammad (S.A.W.); they  should use "Salla Allahu Alaihi Wa Sallam" instead, or they may use the abbreviated form of (S.A.W.) in writing.
