Effects Of Sin
Our Prophet (SWT) mentions that in our body there is piece of meat, a certain part of the body. If this part of the body or the piece of meat is in order then everything else will be in order. Every other part of the body will be in order. And if this part becomes bad then every thing and every other part of the body will go bad. And what is that part? It is the heart of the human being. It is on the heart that every thing leaves an impact. The good deeds and the bad deed and every thing else leave an impact on the heart.
