Be vigilant in life; Protect yourself or those around you; Help others whenever possible; Strive towards piety.

This hadith is about the importance of vigilance and guarding. It narrates an incident where the Prophet Muhammad ﷺ asked for a pious man from his companions to guard him, and Sa’d bin Abi Waqqas came to fulfill this request. This hadith teaches us that we should always be vigilant in our lives, especially when it comes to protecting ourselves or those around us. We should also strive to be like Sa’d bin Abi Waqqas, who was willing to put himself in harm's way in order to protect someone else. Furthermore, this hadith also shows us how important it is for Muslims to help each other out whenever they can; even if it means putting themselves at risk.
