Strive for strong relationships with fellow believers; Support one another in times of need; Work together towards common goals for betterment of society; Forgive mistakes made by others

This hadith by Prophet Muhammad ﷺ explains that the relationship between two believers should be strong and supportive, just like how bricks are used to build a structure. He illustrated this by interlacing his fingers together to show how each brick strengthens the other. This teaches us that we should always strive to have strong relationships with our fellow believers and support one another in times of need. We should also be willing to forgive one another when mistakes are made and work together towards common goals for the betterment of society as a whole.
