All that we are is the result of what we have thought. If people speak or act with evil thoughts, pain follows them. If people speak or act with pure thoughts, happiness follows them, like a shadow that never leaves them.

If you once forfeit the confidence of your fellow citizens, you can never regain their respect and esteem. It is true that you may fool all of the people some of the time; you can even fool some of the people all of the time; but you can't fool all of the people all of the time. -Speech at Clinton, Illinois, September 8, 1854.
If Allah has written for you happiness, no one can steal that from you, and if He has written for your heart to break, then no-one can mend it but He, so always put your trust in Allah.
