"The
eyes are the windows to the soul, so protect your soul from what your
eyes see. If you allow your eyes to wander, be sure that you're allowing
your iman to falter. When your iman falters, it immediately makes you
view your sins as minuscule. When you view your sins as minuscule, the
fear of Allah diminishes. When the fear of Allah diminishes, the hearts
harden. So lower your gaze and protect your soul from what your eyes
see."
