What Kind of Person Makes Fun of Others?

The great scholar Al-Saʿdī, may Allāh have mercy on him, said:

Indeed, making fun of others doesn’t happen except from a heart full of vile characteristics, adorned with every despicable disposition. It’s for this [reason that] the Prophet ﷺ said: “It’s enough evil for a person that he belittles his Muslim brother.”
