Follow religious rituals and observe them properly during special occasions such as 'Id al-Adha by avoiding cutting your hair or trimming your nails when you possess a sacrificial animal .

This hadith teaches us that it is not permissible to cut one's hair or trim their nails after entering the first days of Dhu'l Hijja if they have a sacrificial animal to offer as a sacrifice. This is because it is important for Muslims to be mindful of the rituals associated with this holy month, and ensure that they are properly observed. The Prophet Muhammad taught us that we should take care in our grooming habits during this time, so as not to detract from the importance of offering sacrifices on 'Id al-Adha. By following these teachings, we can ensure that we are honoring this sacred occasion in its entirety.
