Beware! Beware! of acts of disobedience because they have very evil consequences. Beware! Beware! of sins, especially sins that are committed in privacy. Surely competing with Allaah causes a person to fall from the sight of Allaah. The pleasure of disobedience gains nothing but perpetual negligence. As for the believer who is awake (and on his guard), he takes no delight from disobedience. This is because when he begins to take delight from it, his knowledge of its prohibition stands before him. His caution from its consequences also stands before him.
If his cognition (of Allaah) is strong, he sees Allaah with the eyes of his knowledge. His life becomes disturbed at the time when he begins to take delight (from sinning). If the intoxication of his desires overpowers him, the heart is disturbed with his pondering and reflection. If this nature is in his desire, it is only for a moment. Thereafter it is eternal disgrace, continuous remorse, constant crying, and regret over what happened. This continues for a long time to such an extent that even if he is convinced that he has been pardoned, the fear of reprimand still stands before him.”
So away with sins! How ugly their consequences are! And what bad news they bring! Away with desires! If only they could be acquired to the extent of the power of negligence.
