Respect those who do not share your beliefs; Do not underestimate your opponents; Persevere in trying times; Have patience when dealing with others' ideologies; Be resilient when faced with adversity.

This hadith teaches us about the strength and resilience of unbelievers. It is said that the molar tooth or canine teeth of an unbeliever will be as strong as Uhud mountain, which was a mountain in Medina where a battle between Muslims and non-Muslims took place. Furthermore, it is said that the thickness of their skin will be so great that it would take three nights to travel across it. This metaphorically implies how difficult it can be to penetrate through their beliefs and ideologies. It also serves as a reminder for believers not to underestimate their opponents in any situation or circumstance.
