Shaikh Haji Shakeel Ahmed (Allah preserve him) said,

‘Alive person feels the pain of a pinprick and reacts.  Whereas a dead body will never feel or react even if a nail is driven into it.

Similarly, a faithful individual feels the undesirable effects of sinful activity. It makes him uncomfortable. If this does not happen than one should worry about the presence of faith (eman). It is the (spiritual) life/soul of an individual.’
