Transcript of a lecture Darul Arqam, Singapore, 26th November 1998.

The Prophet Muhammad sallallahu `alayhi wa sallam informed us in a very famous tradition, commonly quoted with reference to halal and haram, about the importance of the heart. He said :

"There is in the body a clump of flesh - if it becomes good, the whole body becomes good and if it becomes bad, the whole body becomes bad. And indeed it is the heart."
