Consult with religious scholars first before taking any action related to religion or rituals.

This hadith is narrated by Ibn 'Abbas, which tells us that the Prophet Muhammad ﷺ was asked about a person who had his head shaved before performing a ceremony of Hajj. The Prophet ﷺ replied that there is no harm in doing so. This teaches us to be mindful of our actions and to not do anything without consulting with religious scholars first, as they can provide guidance on what is permissible and what isn't. It also teaches us to be respectful towards religious ceremonies, as they are important for our spiritual growth and development.
