Rejection of the call for Truth is the greatest crime in the eyes of God. If this rejection is of a call given by a prophet, the punishment for this starts right here in this world, just as happened in the case of the communities of ‘Ad and Thamud. The main point of the call for Truth has always been that man should become a worshipper of God. He should associate with the one and only God his feelings of fear and love. But in every age it has happened that the contemporaries of the Prophet opined that his personality was too unimpressive to have been chosen by God as His messenger. Therefore, they refused to accept his words.
