Work together as a team with larger groups for safety & security

This hadith speaks about the optimal numbers for companions, expeditions and armies. According to this hadith, it is advised to have a group of four people when travelling together as companions. When going on an expedition or an army mission, it is better to have a group of 400 or 4000 people respectively. It also mentions that 12000 will not be overcome due to smallness in numbers. This hadith teaches us that having a large enough group can help us achieve our goals more easily and efficiently while also providing safety and security from any potential threats. It also encourages us to work together as a team rather than individually so we can benefit from each other's strengths and skillsets for greater success.
