Practice humility and respect towards others.

This hadith teaches us about the importance of modesty in our faith. It was reported by Salim on the authority of his father that the Prophet (may peace and blessings be upon him) heard a man criticizing his brother for not being modest. In response to this, the Prophet remarked that modesty is an essential part of faith or Iman. This hadith emphasizes how important it is for us to practice modesty as Muslims since it is a fundamental part of our faith. We should strive to always act with humility and respect towards others so we can remain true to our beliefs as Muslims.
