I want Regular Expression to accept only Arabic characters, Spaces and Numbers.
Numbers are not required to be in
Just add 1-9 (in Unicode format) to your character-class:
1-9
^[\u0621-\u064A0-9 ]+$
OR add \u0660-\u0669 to the character-class which is the range of Arabic numbers :
\u0660-\u0669
^[\u0621-\u064A\u0660-\u0669 ]+$
