This is a 1999 letter from Muqtada al Sadr to Saddam Hussein. After Muqtada's brothers and father were murdered by Saddam's henchmen, Muqtada wrote a letter to Saddam, praising him and thanking him for his condolences! He also hoped that the same (murder) would not happen to Saddam's family. Probably Muqtada was afraid for his own life. It's interesting that 9 years ago Muqtada was so afraid of Saddam, the murderer of his father and brothers, and yet now he fights the Americans, the people who overthrew Saddam, and the new Iraqi government.
Thank you Ammu for the forward!
