Refrain from cutting your hair or nails before offering a sacrifice during the month of Dhu al Hijja.

This hadith teaches us that when we see the new crescent of the month of Dhul Hijjah, it is important to not cut our hair or nails until we have offered a sacrifice. The Prophet Muhammad ﷺ was teaching us that when we are performing an act of worship, such as offering a sacrifice, it should be done with full attention and focus. We should not be distracted by other activities such as cutting our hair or nails. This hadith also reminds us to take part in acts of worship during this blessed month and to remember Allah SWT in all that we do.
