Be careful with your glances; Do what is right in Allah's eyes; Strive for self-control; Respect yourself and others; Be aware of Allah's presence.

This hadith speaks about the wrong of looking at something twice. The Prophet Muhammad was speaking to Ali and warned him not to give a second glance, because while you may be excused for the first one, you have no right to a second one. This hadith teaches us that we should be careful with our glances and not look at something more than once as it can lead us into trouble or sinning. We should also remember that Allah is always watching us and knows what we are doing even if others don't see it. Therefore, we should always strive to do what is right in His eyes and avoid anything that could lead us astray from His path.
