Bukhari and Muslim reported that Anas said: "A funeral procession passed by and the people praised the deceased. The Prophet, peace be upon him, exclaimed, 'It is decided.' Then another funeral procession passed by and the people said some bad things about the deceased. The Prophet, peace be upon him, remarked, 'It is decided.' 'Umar asked: 'What is decided?' The Prophet, peace be upon him, answered, 'The one whom you praised is entitled to Paradise, and the one whom you described as bad is entitled to the Hell Fire. You are Allah's witnesses on earth'."
