Narrated Muhammad bin Sirin: "I don't think that a man who degrades Abu Bakr and 'Umar loves the Prophet ﷺ".
The lesson here is that we should always show respect for those who are close to us, especially if they are respected by our beloved ones like our parents or teachers or even religious figures like prophets or imams. We should never degrade anyone in order to make ourselves look better; instead, we should strive for humility and kindness towards others so that we can be closer with Allah SWT through His beloved ones.
