Weep out of fear for Allah, Spend nights in guarding/worshiping/doing good deeds

This hadith is about how to protect oneself from the fire of hell. The Prophet Muhammad ﷺ said that two eyes will never be touched by the fire of hell; an eye which weeps out of fear for Allah, and an eye which spends its nights in guarding in the cause for Allah. Weeping out of fear for Allah means to cry due to feeling overwhelmed with love, respect, and awe for Him. Spending nights in guarding means dedicating time to worshiping God or doing good deeds such as helping others or volunteering at a charity organization. Both these actions are ways that can help us stay away from sinning and ultimately save us from being punished by hellfire on Judgment Day.
