Du'aa ...

I beg Forgiveness of Allah 
My Lord

From all the sins which I have committed ...
Consciously and unconsciously ...
Hidden and evident ...

I repent and ask forgiveness for all my sins ...
Of which I am aware or not aware ...

O Allah ...
You are the Knower of all things unknown ...
And the Veiler of disgrace ...
The Forgiver of sins ... 

There is no power or strength besides Allah ... 
The Exalted ...
The Supreme ...
